ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a spinning reel for fishing which can prevent a fishing line from becoming entangled on the spinning reel during fishing operation and permits a spool to be increased in diameter without increasing the size of the entire spinning reel.
As shown in Japanese Utility Model Publication No. 4-43017 or in
FIG. 34
, in most of conventional spinning reels
1
for fishing, a semiannular-shaped bail
7
is mounted on the leading end portions of a pair of support arms
5
provided in a rotor
3
through two bail support members
9
and
11
. The bail support members
9
and
11
are switching urged to and held at their respective fishing line take-up and play-out positions by a reversal control device
15
which is installed within the storage portion
13
of the support arm
5
.
In such spinning reel
1
, if the bail
7
is turned down to its fishing line play-out position and the terminal tackles of the fishing rod are thrown out, then a fishing line wound around a spool
17
is played out in a spiral manner. On the other hand, if the bail
7
is returned to its fishing line take-up position and the rotor
3
is rotated in a fishing line take-up direction by operating a handle
19
, then the fishing line can be wound around the spool
17
which reciprocates in the longitudinal direction thereof in conjunction with the rotation of the rotor
3
.
However, as shown in
FIG. 34
, in the above spinning reel
1
, since the bail support members
9
and
11
are pivotably supported on the support arms
5
in such a manner that they project greatly outwardly of a cover
21
covering the storage portions
13
, the support arms
5
(including the bail support members
9
and
11
) are increased in thickness and thus in size, and the fishing line is likely to become entangled around the bail support members during the fishing operation of the spinning reel
1
.
Also, in Japanese Utility Model Publication No. 3-74259, there is disclosed a spinning reel
33
in which, an shown in
FIG. 35
, two fitting grooves
27
are respectively formed in the front peripheral portions of a pair of support arms
25
provided in a rotor
23
. Two bail support members
29
and
31
are respectively fitted to the fitting grooves
27
while being returnably journaled on the support arms
25
, and the outer surfaces of the mutually connecting portions of the bail support members
29
,
31
and support arms
25
are formed in such a manner that they are almost flush with each other.
The structure of the spinning reel
33
provides an advantage in that the bail support members
29
and
31
are prevented from projecting radially outwardly from the respective outside surfaces of the support arms
25
. However, the fishing line may still be caught in or bite into clearances between mutually opposing portions, i.e. the leading end portions
25

of the support arms
25
and the stepped portions
29
a
,
31
a
of the bail support members
29
,
31
, during the fishing operation.
Further, since the fitting grooves
27
to be fitted with the bail support members
29
and
31
are formed in the respective front peripheral portions of the support arms
25
, a drawback is pointed out in that the thicknesses of the support arms
25
themselves are increased thereby increasing the outside width dimension L of the support arms
25
.
In general, if the diameter of the spool is increased in a spinning reel, this there provides advantages in that the permanent deformation (which is likely to make the fishing line looped or spiral, not straight) is hardly imparted to the fishing line and that a thumbing operation onto the spool can be carried out easily and smoothly. However, in the spinning reel
33
as shown in
FIG. 35
, in which the support arms
25
themselves are increased in size, if the diameter of the spool
35
in increased for these advantages, then the rotor and the support arms must be further increased in diameter and size. Consequently the entire reel is increased in size and weight, which hinders the smooth fishing operation.
SUMMARY OF THE INVENTION
The present invention aims at eliminating the drawbacks found in the above-mentioned conventional spinning reels. Accordingly, it is an object of the invention to provide a spinning reel for fishing which can prevent a fishing line from becoming entangled during the fishing operation of the spinning reel. Another object of the present invention is to provide a spinning reel for fishing which permits the diameter of a spool to be increased without increasing the size of the entire spinning reel.
In order to attain the above-noted and other objects, the present invention provides a spinning reel for fishing for winding a fishing line onto a spool with a rotor rotatable about an axis, wherein:
the spool includes a front side flange portion, a fishing line winding barrel portion and a rear side flange portion opposite from the front side flange portion with respect to the fishing line winding barrel portion along the axis;
the fishing line winding barrel portion is tapered at an angle of 0.5° to 5° with respect to the axis so that a diameter of the fishing line winding barrel portion gradually decreases from the front side flange portion to the rear side flange portion; and
an axial length of the rear side flange portion along the axis in larger than an axial length of the fishing line winding barrel portion.
The present invention further provides a spinning reel for fishing for winding a fishing line onto a spool with a rotor rotatable about an axis, wherein:
the spool includes a front side flange portion, a fishing line winding barrel portion and a rear side flange portion opposite from the front side flange portion with respect to the fishing line winding barrel portion along the axis;
the fishing line winding barrel portion is tapered with respect to the axis so that a diameter of the fishing line winding barrel portion is gradually decreases from the front side flange portion to the rear side flange portion; and
a rear end of the rear side flange portion is tapered so that a diameter of the rear end gradually decreased rearwardly.
The present invention further provides a spinning reel for fishing for winding a fishing line onto a spool with a rotor rotatable about an axis, wherein:
the spool includes a front side flange portion, a fishing line winding barrel portion and a rear side flange portion opposite from the front side flange portion with respect to the fishing line winding barrel portion along the axis;
the rotor includes a pair of support arms located diametrically opposite from each other with respect to the axis;
a diameter of the front side flange portion relative to a distance defined between outer surfaces of the support arms is set at 0.6 to 0.8; and
a rear end of the rear side flange portion is tapered so that a diameter of the rear end gradually rearwardly.
The present invention further provides a spinning reel for fishing for winding a fishing line onto a spool with a rotor rotatable about an axis, wherein:
the spool includes a front side flange portion, a fishing line winding barrel portion and a rear side flange portion opposite from the front side flange portion with respect to the fishing line winding barrel portion along the axis; and
a diameter of the rear side flange portion relative to a diameter of the front side flange portion is set at 0.95 to 1.05.
The present invention further provides a spinning reel for fishing for winding a fishing line onto a spool with a rotor rotatable about a first axis, wherein:
the rotor includes a pair of support arms and a cover is attached to at least one of the support arms;
said at least one of support arms and said cover cooperatively form a mounting portion for pivotably mounting a base portion of a support member to which a bail is fixed;
an imaginary plane is defined, which contains the first axis and intersects both the support arms;
a peripheral wall is erected from and elongated along a peripheral edge of the mounting portion so that the periph
