A stopper part is formed at one end of the rotating part, an engaging part formed by cutting a part of the rotating part into a semicircular shape is formed at the other end, and a threaded part is formed at the outer end of the engaging part. The connecting pin is rotatably inserted into the drive lever in parallel with the rotation axis, and the long hole of the drive member is fitted into the engagement portion so as to be slidable in the adjustment direction. A locking member is screwed onto the threaded portion to fix the driving member.

[Effect]

In order to connect the lever member and the driving member in the connection structure according to the present invention, first, the rotating part of the connecting pin is inserted into the rotating hole of the lever member from the back side, and the stopper part is brought into contact with the back side of the lever member. The engaging portion is protruded toward the front side, and the long hole of the drive member is slidably fitted into the engaging portion. After adjusting the connection position, the locking member is tightened to the threaded portion of the connecting pin. During this tightening, since the elongated hole of the driving member is fitted into the engaging portion of the connecting pin, the connecting pin does not rotate together, so there is no need to fix the connecting pin as in the conventional case. As a result, connection workability is greatly improved.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 are diagrams for explaining a connection structure between an outer lever and a control cable according to an embodiment of the present invention.

In the figure, 1 is a transmission case, and although not shown, a manual valve is disposed inside the case 1, and a manual valve lever for switching the valve is connected to the manual valve. A manual valve shaft 2 is fixed to the valve lever, and one end of the manual valve shaft projects outward from the side wall 1a of the transmission case 1. An upper end 3a of an outer lever 3 as a lever member is fitted into this protrusion 2a and fixed by a lock nut 2b. Further, a rotation hole 3c is formed in the lower end portion 3b of this outer lever 3.

A cylindrical rotating portion 4a of the connecting pin 4 is rotatably inserted into the rotating hole 3c of the outer lever 3. A disc-shaped stopper part 4b is integrally formed at one end of the rotating part 4a, an engaging part 4c is formed at the other end, and a threaded part 4 is formed at the outer end of the rotating part 4a.
d is integrally formed. The engaging portion 4c is a flat plate formed by cutting the lower portion of a cylinder into a semicircular shape as shown in the drawing.

An adjustment slot 5a of the cable end 5 is fitted into the engagement portion 4c so as to be slidable in the longitudinal direction thereof. This cable end 5 is connected within the dust boot 6 to a control cable. Also, the cable end 5 of the threaded portion 4d
A lock nut 7 is screwed onto the portion that protrudes outward from. Thereby, the outer lever 3 and the cable end 5 are connected to each other so that they can rotate and the cable length can be adjusted. The length b of the rotating portion 4a of the connecting pin 4 is set longer than the gap a between the connecting pin 4 and the side wall 1a of the transmission case 1.

Next, the effects of this embodiment will be explained.

In order to connect both members 3 and 5 in the structure of this embodiment, first, the outer lever 3 is rotated outward of the transmission case 1 as shown by the two-dot chain line in FIG. 4 into the rotation hole 3c from the transmission case 1 side, and return this outer lever 3 to its original position. Then, the engaging portion 4c of the connecting pin 4
After fitting the elongated hole 5a of the cable end 5 into the long hole 5a of the cable end 5 and temporarily tightening the lock nut 7 to the threaded part 4d of the connecting pin 4 and adjusting the connection position to ensure the operation of the manual valve, the lock nut 7 is properly tightened. Tighten and secure.

When the cable end 5 is attached to the engaging portion 4c, the connecting pin 4 does not come off the outer lever 3 and fall because the transmission case 1 acts as a rearward stopper. Furthermore, when tightening the lock nut 7, since the engaging portion 4c engages with the elongated hole 5a of the cable end 5, the connecting pin 4 does not rotate. There is no need to fix it for As a result, the work of connecting both the members 3 and 5 can be made very easy, and the workability can be improved.

In the above embodiment, the connection between the outer lever of an automatic transmission and the control cable was taken as an example, but the scope of application of the present invention is not limited to this, and the point is to connect the outer lever of an automatic transmission to a control cable that is rotatable and It may be applied to a case where the connection length can be adjusted, and is particularly effective when it is difficult to secure a space for inserting a tool such as a spanner on the back side of the connection part.
