2. Description of the Related Art For example, in an automatic transmission for a vehicle, a shift lever and an automatic transmission are connected by a push-pull cable or the like for switching a range or the like. An example thereof is described in Japanese Utility Model Laid-Open No. 62-108130, and a brief description thereof will be given. In FIG. 7, reference numeral 1 indicates a control lever, which is attached to a bracket 2 attached at a position deviated from the center of rotation thereof. The hole 3 is formed. On the other hand, a cable end 5 is provided at the end of the control cable 4, and a connecting pin 6 is rotatably attached to the cable end 5. The connecting pin 6 is formed by inserting the shaft portion 7 into the cable end 5 and preventing it from coming off by the β pin 8, and forming a rectangular portion 10 formed on the surface of the flange 9 formed at the shaft end on the side opposite to the shaft portion 7. The non-rotatable portion is fitted in the long hole 3. Further, a threaded portion 11 is provided at the center of the rectangular portion 10, and a nut 12 is screwed into the threaded portion 11 to fix the connecting pin 6 to the bracket 2.

[0003]

In the structure using the connecting pin 6 described above, the connecting pin 6 is connected to the cable end 5.

Fixed to 1. Therefore, in the above-mentioned conventional structure, as a working space for connecting the control cable 4 to the control lever 1, a working space corresponding to the length from the flange 9 to the tip of the screw 11 is provided on one side of the bracket 2. Although necessary, for example, in view of the demand for making the space between the components as narrow as possible in order to secure the vehicle interior space, it is possible to secure the working space on one side of the bracket 2. In some cases, it is difficult, and even if the minimum working space can be secured, the work is done in a narrow space, which causes a problem of poor operability.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a control mechanism in a power transmission device in which the control cable is easily assembled to the control lever.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a control of a power transmission device in which a control cable for transmitting an operating force to the power transmission device is connected to a control lever which is rotated.

EXAMPLES The present invention will now be described in detail based on examples. 1 and 2 are views showing an embodiment of the present invention. The example shown here is an example of a control mechanism in which a control cable 21 is connected to a shift lever 20 for an automatic transmission. In the prescribed place of
A stay portion 22 as a connecting portion made of a plate-shaped member is attached. The stay portion 22 is made of, for example, a metal plate, and is bent in the axial direction of the control cable 21 as shown in the figure. Further, the tip portion thereof is bent at a substantially right angle, and the bent portion is bent. The front end portion serves as a stopper portion 23. A long hole 24 is formed between the intermediate portion of the stay portion 22 and the stopper portion 23 as an engaging hole formed along the stopper portion 23 and in a direction parallel to the axial direction of the control cable 21. . This long hole 24
Since the stopper portion 23 is bent in a direction substantially orthogonal to the axial direction of the control cable 21, the stopper portion 23 opens at the boundary portion (corner portion) with the stopper portion 23 in the axial direction of the control cable 21. There is. Reference numeral 24a indicates the opening.

An engaging pin 25 is attached to the end of the control cable 21. This engagement pin 25
Is provided so as to project in a direction orthogonal to the axial direction of the control cable 21, and like the conventional connecting pin 6, a shaft portion 27 is provided on one end side with the flange portion 26 as a center. The shaft portion 27 is rotatably inserted into the cable end 28, and the β pin 29 is inserted into the tip portion of the shaft portion 27 to prevent the shaft end 27 from coming off from the cable end 28. Further, a rectangular portion 30 having an outer surface having an interval substantially equal to the width of the elongated hole 24 is formed on the other end side centering on the flange portion 26, and the screw portion 31 is further provided at the central portion of the rectangular portion 30. Is projected.
The length of the screw portion 31 is set to be equal to or less than the length of the long hole 24 in the stopper portion 23.

Control cable 2 with the above-mentioned mechanism
The connecting operation for the first stay portion 22 will be described.
First, as shown in FIG.
Attach it to 8. That is, the shaft portion 27 is inserted into the cable end 28, and the β pin 29 is attached to the protruding end from the cable end 28 to prevent the shaft end 27 from coming off.

In this state, the cable end 28 is positioned in front of the stay portion 22, and when the control cable 21 is moved to the stay portion 22 side from this state, the engaging pin 2
When the tip portion of the stay portion 22 is bent to form the stopper portion 23, the portion 5 enters the elongated hole 24 that is open to the tip end side from the opening portion 24a. In that case, the engagement pin 25 is rotated so that the two parallel surfaces of the rectangular portion 30 come into contact with the inner edge of the elongated hole 24. And screw part 3
For example, a nut 32 with a seat is screwed into
Is fixed to the stay portion 22. That is, the screw portion 31 and the nut 32 serve as fixing means.

Therefore, in the structure described above, the engagement pin 2
Since it is not necessary to shift the engagement pin 25 to one side of the stay portion 22 when inserting 5 into the slot 24, the engagement pin 25 is secured to one side portion of the stay portion 22 with the peripheral component 33. The width of the required space may be about the dimension from the flange portion 26 to the tip of the shaft portion 27. Also, the long hole 2 of the engaging pin 25
Since the control cable 21 may be fed in the axial direction, the insertion into the cable 4 is not particularly difficult. Therefore,
Also, with the control mechanism having the configuration shown in FIG. 2, the assembling work can be easily performed even if the space between the components is narrowed to the minimum.

In the configuration shown in FIGS. 1 and 2, the control cable 21 and the shift lever 20 are changed by changing the fixing position of the engaging pin 25 in the elongated hole 24.
The relative position of and can be adjusted. Further, since the stopper portion 23 is formed by bending in the direction orthogonal to the axial direction of the control cable 21, even if the nut 32 is loosened, the control cable 21 does not come off from the shift lever 20.

By the way, in the present invention, the shape of the engaging hole into which the engaging pin is inserted is not limited to the shape shown in the above-mentioned embodiment. The point is that the engaging pin to be inserted inside is oriented in the radial direction. It is only necessary to open it, and some examples are as follows.

That is, the example shown in FIG. 3 has a shape obtained by cutting out the above-mentioned stopper portion 23, and the long hole 24A of the stay portion 22A shown here is directly opened in the axial direction of the control cable.

The example shown in FIG. 4 is an example in which the opening portion of the elongated hole 24B is formed above the stay portion 22B. With this structure, if the engaging pin 25 is moved upward and then lowered at the opening of the slot 24B, the engaging pin 25 is moved to the slot 24B.
And can reduce the space for assembling as in the example shown in FIGS. 1 and 2.

In the example shown in FIG. 5, the elongated hole 24C formed in the stay portion 22C is opened rearward with respect to the axial direction of the control cable 21. In any of the configurations shown in FIG. 5 and FIG.
B and 24C serve as a stopper.

Further, the example shown in FIG. 6 is an example in which the front end portion of the metal plate which is the material of the stay portion 22D is bent to form a long hole 24D which is opened obliquely downward with respect to the axial direction of the control cable 21. . Even with such a configuration, the engagement pin 25 can be inserted as in the example shown in FIGS. 1 and 2, and the tip of the metal plate is slightly bent in the direction of closing the opening. Therefore, this bent part F
Functions as a stopper for preventing the engagement pin 25 from coming off.

[0018]

As described above, according to the present invention,
When attaching the engaging pin to the connecting portion, it is not necessary to move the engaging pin and the end portion of the control cable to which the engaging pin is attached to one side portion of the connecting portion, that is, the direction orthogonal to the axial direction of the control cable. Since it does not need to be moved to a small space, the space for only the assembly work may be small, therefore the space between the control mechanism parts can be reduced to satisfy the demand for miniaturization, and the connection or assembly in a narrow space can be achieved. The attaching work can be easily performed.
