である。 A wire connection structure for a wire operation lever device is disclosed in Japanese Utility Model Application Publication No. 118759/1983. In this method, a connector having an axis parallel to the pivot shaft is provided between opposing walls of a lever body rotatably connected to the pivot shaft, and a connector extends in the radial direction from the connector. The operating wires are connected to each other, and both ends of the connector in the axial direction are formed into bosses having a smaller diameter than the middle part in the axial direction, and are rotatably supported in support holes in the opposite wall of the lever body. It is something that

連結子はレバー本体に対し相対回動自在とされて
いる。しかし、連結子のボスはレバー本体の支持
孔に直接支持されているため、その相対回動がい
まひとつ円滑でなく、レバー本体の繰返し回動で
ワイヤが繰返し屈折され、ワイヤ切断されるとい
う問題があつた。 In the conventional type mentioned above, the lever body is rotated to prevent bending or shearing force from being applied to the wire.
The connector is rotatable relative to the lever body. However, since the boss of the connector is directly supported by the support hole of the lever body, the relative rotation thereof is not smooth, and there is a problem that the wire is repeatedly bent and broken due to repeated rotation of the lever body. It was hot.

向壁内側面との間の摺接により、やはり連結子の
回動が規制されてしまうという問題がある。 Therefore, it is possible to interpose a bearing member between the boss of the connector and the support hole of the lever body, but if the bearing member is simply made into a cylindrical shape, the bearing member will come out by caulking both ends of the boss, etc. This is troublesome and requires a separate stopping means. In addition, the boss portions at both axial ends of the connector are made smaller in diameter than the central portion to prevent the connector from coming off from the lever body. However, if the bearing member is a simple cylinder that is fitted onto the boss portion, There is also a problem in that the rotation of the connector is restricted due to the sliding contact between both side surfaces of the central portion in the center direction and the inner side surface of the opposing wall of the lever body.

ができ、ワイヤ９の切断を防止できる。 According to the above configuration, the bearing member 13 has a collar that is connected to the inner surface of the opposing wall 11 of the lever body 6 and the connector 10.
Because it is located between the center of the axis and both sides of the
There's no getting out of Boss 12. In addition, the bush 13 has a cylindrical main body that is connected to the boss 12 and the support hole 1.
In addition to preventing sliding contact between the lever body 6 and the lever body 6, the brim prevents sliding contact between the inner surface of the opposing wall 11 and both sides of the axially central portion of the connector 10.
When the connector 10 is rotated, the connector 10 can be rotated smoothly, and the wire 9 can be prevented from being cut.
