BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a spinning reel, and more particularly to a spinning reel having a screw shaft for reciprocating a spool disposed on the spinning reel.
2. Description of the Related Art
A spinning reel typically includes a reel main body, a rotor rotatably supported by the reel main body, and a spool supported by the reel main body. Fishing line is wound around the outer periphery of the spool.
The reel main body is equipped with a handle and a handle shaft, with a face gear fixed to the handle shaft. The face gear is meshed with a pinion gear, with an end portion of the pinion gear fixed to the rotor. An intermediate gear is fitted to an end portion of the screw shaft and is meshed with the pinion gear. An end portion of the pinion gear is supported by a bearing portion and is disposed within the circumference of the face gear. A slider is engaged with a spool shaft, and the screw shaft moves the slider along the screw shaft, thereby reciprocating the spool and the spool shaft.
The rotor includes a pair of bail supporting arm portions, with a bail and a line roller for guiding the fishing line around the outer periphery of the spool being disposed between both the bail supporting arm portions.
With this type of spinning reel, when the handle is rotated by the user, the rotor spins around the periphery of the spool and the spool reciprocates, thereby allowing the fishing line to be uniformly wound around the outer periphery of the spool.
The type of spool reciprocating mechanism described above allows the range of reciprocal motion of the spool to be increased without increasing the diameter of the face gear or the overall size of the reel body. However, when the diameter of the face gear is small, the gear ratio is such that operation of the handle is often not optimal. In other words, a spinning reel with a smaller face gear requires the user to apply more force to spin the rotor than a spinning reel with a larger face gear.
It is desirable for an end portion of the pinion gear to be supported by a ball bearing mechanism, so that the force needed to spin the rotor could be reduced. However a small face gear does not provide sufficient space for a ball bearing mechanism to be disposed at the end portion of the pinion gear adjacent to the face gear.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to reduce the force needed to operate a spinning reel by enhancing the efficiency of its rotor mechanism.
Another object of the present invention is to provide sufficient space within a spinning reel to allow an end portion of a pinion gear to be supported with a ball bearing mechanism.
According to one aspect of the present invention, a spinning reel includes a reel main body, a rod attachment portion for attaching the spinning reel to a fishing rod, a handle shaft rotatably supported by the reel main body, a spool shaft supported in the reel main body, a rotor shaft, a rotor, a face gear, a pinion gear, and a reciprocating mechanism. The face gear includes a disc portion fixed to the handle shaft and an annular ring portion formed on an axial face of the disc portion. The annular ring portion includes gear teeth disposed on an axial surface of the annular ring portion. An annular recess is defined by the inner edges of the annular ring portion disposed on the face gear. The rotor shaft includes a pinion gear formed thereon, and the pinion gear engages the face gear. The rotor shaft is rotatably supported in the reel main body generally perpendicular to the handle shaft. The rotor is rotatably supported by the rotor shaft and guides the fishing line around the outer periphery of the spool. The distance between the axial center of the handle shaft and the center of a rod attachment face connected to the rod attachment portion is less than or equal to 85 mm., and the outer diameter of the face gear is equal to or greater than 40% of this distance.
According to another aspect of the present invention, a spool is su
