ABSTRACT:

TECHNICAL FIELD
The invention relates to an operating apparatus comprising an improved connecting structure between an operator and a member to be operated (hereinafter briefly called as “member”).
TECHNICAL BACKGROUND
Conventionally, in an operating apparatus to be used to serve to control, for example, lights, wipers, washers, air conditioners and others, as shown in
FIG. 4
, an operator
1
and a member
2
are furnished. The member
2
is held in a case
3
, and under this condition the operator
1
which is provided therein with a sleeve
4
is fitted on a shaft part
2
a
of the member
2
whose one part is projected from the case
3
, so that the operator
1
is connected to the member
2
.
In this state, the sleeve
4
is, as shown in
FIGS. 5 and 6
, is cut at both sides into cut portions
6
and is defined with a part
5
which protrudes inward thereof. When the operator
1
is fitted as mentioned onto the shaft part
2
a
of the member
2
, the protruded part
5
is straightened by the shaft
2
a
from a state shown with a two-dotted line in
FIG. 5
to a state shown with a solid line. Due to a restoring force from this straightened state to the protruded state, the protruded part
5
is pressed to the shaft
2
a,
and due to friction thereby the operator
1
is prevented from slipping out.
When a user of this apparatus holds the operator
1
to rotate, push or pull, the member
2
is accordingly rotated, pushed or pulled to carry out controllings as mentioned.
However, when the user pulls the operator
1
, if the friction force at the protruded part
5
of the sleeve
4
effecting to the shaft
2
a
of the member
2
could not stand against the pulling force, the operator
1
would be probably slipped out. In particular, when a pulling operation is included in operating modes of the operator
1
, it is pulled more frequently, so that slipping-out is more possibly.
Such a structure particularly wants a part as a sleeve having the protruded part
5
together with the cut portion
6
and invites high producing cost.
DISCLOSURE OF THE INVENTION
In view of these circumstances, the invention has been realized, and accordingly it is an object to offer an operating apparatus which can prevent the operator from slipping out when it is pulled, and can be produced at lower cost.
For accomplishing the object, an operating apparatus of the invention is furnished with an operator and a member to be operated by manipulating the operator, and is characterized by providing
a part to be engaged furnished at the operator,
an engaging part furnished at the member to be operated, the engaging part being engaged with the part to be engaged in a manner that it is returned under being outward bent by pushing the operator thereinto, and being connected with the member such that the member to be operated is moved integrally by an at least pulling operation of the operator, and
a checking member furnished to stand outside of the engaging member when the operator is pulled so as to check the outside bending of the engaging member at this standing position.
According to the present instrument, when the operator is pulled, the checking member stands outside of the engaging part, and the engaging part is prevented from getting out of a part to be engaged in that the checking member checks the engaging part from the outside bending.
