Description

[Detailed Description of the Invention] This invention relates to a dust cover that is fitted and attached to a socket such as a ball joint.

Conventional dust cover! As a means of attachment, an outer circumferential groove is provided on the upper convex end surface of the socket, and after the component is assembled, the member cover is caulked and fixed, a dust cover is fitted into the outer circumferential groove, and further clamped. Although it is assumed that the assembly structure is complete, there was a problem in terms of man-hours in the work of attaching the dust cover and clamp, and this proposal was established as a means to solve this problem.

Next, the main idea will be explained with reference to the drawings.

Reference numeral 1 denotes a main body of a Custo cover, which is released from an elastic body (for example, a rubber product), and has a boss portion 2 formed at its lower part.

3 is a reinforcing ring inserted into the boss portion 2.

4 is a socket for the ball joint 5; 6 is a support plate for the ball joint 5 which is pressed by a spring 7; and 8 is a cover for members such as springs, which is caulked to the lower part of the socket 4.

The dust cover main body 1 is fixed to the upper part of the socket 4 of the ball joint with a fitting clasp 9 on the boss portion 2.

Since the present invention is constructed as described above, when the dust cover body 1 and the socket 4 are assembled, the boss part 2 of the cover body is compressed and fitted into the upper part of the socket 4 so that the boss part A repulsive force is generated and a crimp with the socket is obtained, and by fixing this cover assembly part with caulking 9, the inside of the mechanism is completely isolated from the outside, preventing dust, muddy water, etc. from entering the inside. I can do it.

Further, by providing a reinforcing ring 3 on the boss portion 2, it is possible to prevent the dust cover from falling into the inside of the main body 1.

This reinforcing ring 3 has a flat plate shape 3' as shown in FIG.
It is also possible to do this.

Incidentally, as mentioned above, in these conventional examples, as shown in the drawing (Fig. 4), an outer peripheral groove is provided in the upper part of the socket (a), a dust cover C is fitted into this, and the dust cover C is further tightened with a clamp d. This is being implemented.

As is clear from the above, in this case, when assembling the dust cover and socket, a fixed assembly can be obtained by utilizing the elasticity of the cover boss part and a very simple structure and operation of caulking, and the reinforcing ring of the boss part is stabilized. This significantly improves the workability of attaching the dust cover by maintaining its properties.
It has great practical value as a product with enhanced functionality.
