BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a clip for preventing a clevis pin for connecting a master cylinder to a brake pedal of a motor vehicle.

[0002]

2. Description of the Related Art Conventionally, a clip C as disclosed in Japanese Utility Model Laid-Open Publication No. 64-36714 has been used to prevent a clevis pin K connecting this type of brake pedal and a master cylinder M from coming off. 11 to 13 show such a clip C and a method of using the same. The clip C shown in FIG. 11 is provided on one side of a cylindrical portion 102 having a shaft hole 101 in which a clevis pin K is accommodated. A flange 103 is disposed on the opposite side of the cylindrical portion 102 from the flange 103, and a pressing piece 104 bent from the raised upper end onto the shaft hole 101 of the flange 103 is provided so as to protrude therefrom. In addition, a locking piece 105 is provided on the outer periphery of the cylindrical portion 102 so as to rise toward the flange 103. Then, the cylindrical portion 102 of the clip C is inserted into a mounting hole H provided in the pedal rod P, and the inserted cylindrical portion 102
Between the locking piece 105 and the flange 103, and is locked and fixed with the hole edge of the mounting hole H held therebetween, inserted into the shaft hole 101 of the clip C, and pivotally supporting the master cylinder M. The configuration is such that the pin head of the clevis pin K is supported by the holding piece 104.

[0003]

Since the conventional clip C is mounted on the clevis pin K itself to prevent the clip C from coming off, the conventional clip C always moves following the movement of the clevis pin K. Although the clevis pin K can be securely pressed into the pin head, there is an inconvenience that the clevis pin K is liable to be worn or damaged by rotation of the shaft around the clevis pin K generated when the pedal P is operated. or,
Since the clevis pin K is used in a state that the clevis pin K is closely fitted to the clip C, it is difficult to remove the clevis pin K during maintenance or the like.

[0004] In view of the inconvenience of such conventional clips, the present invention constitutes a clip for preventing the clevis pin from coming off separately from the clevis pin constituting the shaft rotating portion, thereby preventing abrasion and breakage of the clip. An object of the present invention is to provide a clevis pin retaining clip capable of easily attaching and detaching the clevis pin.

[0005]

The clip C of the present invention is:
In order to achieve such an object, a main body 1 closely contacting the side surface of the brake pedal rod P and the pedal rod P projecting from the main body 1 and between the main body 1 and the main body 1 are provided.
A mounting leg 3 having an elastic locking piece 2 for holding a hole edge of a mounting hole H provided in the main body 1 is provided so as to be parallel to the mounting leg 3, and the pedal rod P And a resilient piece 5 extending from the main body 1 toward the pin head of the clevis pin K axially passed through the pedal rod P.

[0006]

The clip C of the present invention is fixed at a position separated from the clevis pin K, and is separated from the movement of the clevis pin K as a shaft pin. Absent.
The main body 1 of the clip C is attached to the pedal rod P by the mounting leg 3.
And the protrusion 4 is in contact with the side edge of the pedal rod P, so that the clip C attached to the pedal rod P is prevented from moving in the rotational direction. .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a typical embodiment of a clip C for retaining a clevis pin according to the present invention will be described in detail. The clevis pin retaining clip C is used to prevent the clevis pin K connecting the brake pedal of the vehicle and the master cylinder M from coming out by repeated depression of the brake pedal. A main body 1 that is in close contact with the main body 1, a mounting leg 3 protruding from the main body 1, a projecting piece 4 protruding from the main body 1 in parallel with the mounting leg 3, and a mounting leg 3. An elastic piece 5 is provided so as to protrude in an inclined manner from the main body 1 on the side opposite to the side in which the mounting leg 3 protrudes. Such a clip C is preferably a plastic molded product by injection molding in view of maintenance of the elastic mounting state by the mounting leg 3, support of the pin head of the clevis pin K by the elastic piece 5, and molding cost.

First, the main body 1 has a flat mounting side surface 1a which is in close contact with the side surface of the brake pedal rod P, and the lower side of the side surface 1b opposite to the mounting side surface 1a gradually projects to the side. In addition, a bottom surface 1c from the side surface 1b toward the side surface 1a is an inclined surface that gradually rises toward the side surface 1a, so that the space for mounting the master cylinder S and inserting the clevis pin K can be widened. .
The main body 1 has a configuration in which protruding walls 1e are formed on four sides on both sides of the partition wall 1d in order to reduce molding costs.
Next, the projecting piece 4 protruding from the side of the side surface 1a so as to be flush with the upper surface 1f of the main body 1 is also formed to protrude to the side of the main body 1, and this projecting piece 4 is projected. A support wall 1g is provided from the protruding wall 1e on the mounting side surface 1a of the main body 1 toward the portion 4a. The projecting piece 4 has a partition wall of the main body 1.
It has a partition wall 4b which is continuous with 1d and the support wall 1g, and has concave portions 4c on both sides. Further, the mounting leg 3 has a tapered cylindrical shape, and the elastic locking piece 2 is provided in the cylinder axis direction. The elastic locking piece 2 is directed from the distal end side to the main body 1 side in the notch of the mounting leg 3, and the distal end side projects outside the mounting leg 3. Further, the elastic piece 5 protruding from the position where the side surface 1b and the bottom surface 1c of the main body 1 intersect toward the side where the mounting leg 3 is provided has a configuration in which the tip side gradually expands downward. The free end is a rising portion 5a that rises upward, and the upper end of the rising portion 5a is a jaw 5b bent toward the mounting leg 3.

The clip C having the above-mentioned structure inserts the mounting leg 3 into the mounting hole H of the brake pedal rod P, and the mounting hole is provided between the elastic locking piece 2 of the leg 3 and the main body 1. H
The mounting side surface 1a is attached to the side surface of the pedal rod P in such a manner that the hole edge is sandwiched. When the clip C is attached to the pedal rod P, the projecting piece 4 of the clip C is in close contact with the side edge of the pedal rod P, and the free end of the elastic piece 5 of the clip C is The clevis pin K, which assembles the cylinder M with the cylinder, is positioned above the pin head. The clip C attached to the pedal rod P in this manner is stably held on the pedal rod P by the mounting leg 3 and the projecting piece 4.
The detachment of the clevis pin K is reliably prevented by the elastic piece 5 without causing a displacement or the like of the mounting clip C. Further, a protruding portion 4a is further provided on the surface of the protruding piece 4 to function as an operating surface of the switch S of the tail lamp.

[0010]

[Effect of the Invention] The clevis pin retaining clip according to the present invention can prevent the clevis pin from being stably retained without any wear or damage even when the pedal rod is repeatedly used, because of the above-described characteristic configuration. Since the mounting position is different from that of the clevis pin K, the operation of extracting the clevis pin K is easy, which is convenient for the maintenance of the pedal portion. Further, since the projecting piece 4 is provided, the mounting clip C is not displaced, and the pin head of the clevis pin K is always covered with the elastic piece 5 and a good operation surface of the switch S of the tail lamp is provided. be able to.
