この考案はボールジヨイントのソケツトに圧入
嵌装するダストカバーに関するものである。[Detailed Description of the Invention] This invention relates to a dust cover that is press-fitted into a socket of a ball joint.

ール性の向上を図ろうとするものである。 Conventionally, the ball joint dust cover used for automobile tie rods and suspensions has a flat retaining ring molded at the bottom of the dust cover, and when this is press-fitted into the ball joint socket, the ring tightens in the direction of tension. Due to the lack of spring properties, deformation is likely to occur, and the dust cover may even come off. In addition, some have notches at appropriate intervals along the inner circumference of the ring to strengthen the contact with the outer circumference of the socket, but this is said to cause warping due to lack of rigidity, causing problems with sealing performance. . In order to eliminate these existing deficiencies, this project prevents the dust cover from coming off due to deformation such as warpage due to lack of spring strength or lack of rigidity of the ring after press-fitting into the socket of the conventional product, and further improves stable fitting. This is an attempt to improve sealing performance.
次に本案の実施例を図面について説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.

補強環である。 Reference numeral 1 denotes a rubber dust cover main body, which is not shown in the drawings, but is known to be fitted into a socket of a ball joint. Reference numeral 2 denotes a cover attachment portion to a socket in a large opening 3 at the bottom of the main body, and a hard elastic ring 4 for preventing the cover from coming off is molded into the attachment portion 2. This ring 4 is constructed by integrally forming a continuous cylindrical portion 42 on the inner diameter side of an annular flat plate portion 41, with the upper end thereof forming a bent portion 43 reaching the large opening portion 3 side. Therefore, the bent portion 4
3 may have any planar shape (see FIG. 1) or conical tube shape (see FIG. 2). 5 is an upper reinforcing ring of the cover body 1.

状部を介して受けるようになる。 Now, in the present invention, in the above structure, when the dust cover main body is fitted into the socket of the ball joint, since the ring 4 is made of hard elastic material, the bent part 4 is press-fitted into the outer diameter part of the socket.
3 is directly press-fitted and is continuous with the cylindrical portion 42 of the ring, so that the elasticity of the cylindrical portion is also added, and the restoration pressing force to the press-fitted portion becomes strong. or,
Since the cylindrical part 42 has a rubber part between it and the socket outer diameter cylindrical part, by configuring the rubber part in advance to be press-fitted, the sealing performance is improved and the cylindrical part of the ring is removed when the dust cover is press-fitted. Since the ring can be press-fitted while maintaining an even gap between the ring 42 and the socket outer diameter cylindrical portion, deformation and warping of the ring that occur during conventional press-fitting can be prevented. Further, the annular flat plate portion 41 of the ring receives a load in the press-fitting direction from a press-fitting jig or the like through the rubber-like portion when the dust cover is press-fitted.

ある。 As is clear from the above, in this case, a hard elastic ring for preventing the ring from coming off is formed into a continuous integral structure of an annular flat plate part, a cylindrical part, and a bent part, and is molded on the large opening side of the lower part of the dust cover main body. It eliminates deformation and warping, ensures prevention of separation, and shows great results in improving sealing performance.
