Abstract

PROBLEM TO BE SOLVED: To facilitate visual check of whether a member for preventing a connection pin from falling is set, by providing the connection pin and a snap pin in contact with a top face of the head of the connection pin and thus restricting the connection pin, after assembled with lever assembly, to moving in the axial direction. SOLUTION: This lever has a connection pin 30 for connecting a shaft and lever assembly 20, and a snap pin 43 to be assembled to the lever assembly 20. The connection pin 30 comprises a head portion 31 and an axial portion 32, and the snap pin 43 is formed U-shaped by bending a small-diameter bar in one plane at both ends thereof. The connection pin 30 after assembled is restricted to moving in the axial direction because one part of the head portion 31 contacts the periphery of a hole 23 on the lever assembly 20, and the other part contacts parallel portions 41, 42 of the snap pin 43. Therefore, it is possible to check visually whether the snap pin 43 is assembled in advance or not.

The chrysanthemum washer 4a is attached to the jig and the hole 2a of the lever assembly 2 is provided.
The lever assembly 2 and the shaft 1 are assembled by inserting the connecting pin 3 through the lever assembly 2 and the chrysanthemum washer 4a. Alternatively, as shown in FIG. 9, a hole position 2 a of the lever assembly 2 and a hole position 1 a of the shaft 1 are attached to a jig (not shown).
The lever assembly 2 and the shaft 1 are assembled by assembling (inserting) the snap nut 4b to the lever assembly 2 and inserting the connecting pin 3 through the lever assembly 2 and the snap nut 4b.

[0003]

However, the above-mentioned conventional shift lever device has the following problems. Since the chrysanthemum washer 4a and the snap nut 4b for preventing the connection pin 3 from coming off are assembled on the lever assembly 2 on the side opposite to the side where the connection pin 3 is inserted, the chrysanthemum washer 4a or the snap nut is inserted when the connection pin 3 is inserted. 4
It is difficult to visually check whether or not b is set on the jig. Since a jig is required for assembly, the facility cannot be simplified. If the center of the chrysanthemum washer 4a or the snap nut 4b is displaced from the hole position 2a of the lever assembly 2 and the hole position 1a of the shaft 1 when the connecting pin 3 is inserted,
There is a possibility that the retaining force may be reduced, and the reliability of preventing the connecting pin from falling off may be reduced. In order to prevent the drop of the retaining force, in the case of the chrysanthemum washer 4a, the accuracy of the setting jig is required, and in the case of the snap nut 4b, the accuracy of the insertion amount into the lever assembly 2 is required. SUMMARY OF THE INVENTION An object of the present invention is to provide a shift lever device capable of easily confirming visually whether or not a member for preventing a connection pin from coming off is set. Another object of the present invention is that, in addition to the above objects, there is no need for high-precision centering of the connecting pin with the connecting pin of the member for preventing the connecting pin from coming off. It is an object of the present invention to provide a shift lever device that can prevent the shift lever device from coming off.

[0004]

The present invention to achieve the above object is as follows.

A shift pin device having a snap pin that contacts the top surface of the portion and restricts movement of the connecting pin in the axial direction. (2) a shaft rotatable in a shift direction, a lever assembly rotatably connected to the shaft at a lower portion in a select direction, and a shaft and a lever assembly having a head portion and a shaft portion. A connecting pin to be connected,
And a snap pin that is mounted on the lever assembly and that contacts the top surface of the head of the connection pin after the connection pin is mounted on the lever assembly to restrict the movement of the connection pin in the axial direction. Lever device. (3) The shift lever device according to (1) or (2), wherein the head portion of the connection pin is formed with a tapered portion whose diameter increases from the shaft portion side toward the head end side. (4) The snap pin is formed of a curving member or a bending member that can be expanded and contracted, and the movement in the vertical direction and the movement in the axial direction of the connection pin are regulated by the lever assembly (1) or (2). Shift lever device.

In the shift lever devices of (1) to (4), since the shift lever device comes into contact with the head of the connecting pin, it is assembled on the same side as the connecting pin insertion side with respect to the lever assembly, and whether or not there is a snap pin is present. The visual confirmation is easy. In addition, since the snap pin is assembled to the lever assembly, it is not necessary to fix the snap pin with a jig or the like.
The assembly equipment can be simplified. In the shift lever device of the above (3), since the tapered portion is formed at the head of the connecting pin, when the snap pin is assembled to the lever assembly and then the connecting pin is pushed in, the tapered portion of the connecting pin head is used. The snap pin is pushed out so that the connecting pin head can pass through the snap pin. After the passage, the snap pin contracts by elastic force and comes into contact with the top surface of the connection pin head to restrain the connection pin from coming off. In the shift lever device of the above (4), since the snap pin is formed of a curving member or a bending member which can be expanded and contracted, the snap pin is pushed and expanded by the connecting pin when inserting the connecting pin, and returns to the original state after the insertion of the connecting pin. ,
The connecting pin is held down by contacting the top surface of the connecting pin head. Even if the center of the snap pin and the connecting pin are not aligned, the snap pin can expand, and after contraction, can hold down the top surface of the connecting pin head. Therefore, centering such as a chrysanthemum washer and a snap nut is unnecessary. In addition, since the movement of the snap pin in the vertical direction and the connection pin axial direction is restricted by the lever assembly,
After inserting the connecting pin, it does not come off the lever assembly.
