がスタッド嵌着部１８から抜ける問題がある。Problems to be Solved by the Invention The dust cover 20 is formed of an elastic material such as rubber, and the dust cover 20 has an axial height that changes from the free shape shown in FIG. 2 to the installed shape shown in FIG. Since it is attached to the socket 11 and the ball stud 15 in a compressed state, the dust cover small opening 21 is opened by its own repulsive force.
There is a problem that the stud may come off from the stud fitting portion 18.

２５が設けられている。In its free state, the dust cover 20 has an approximately bell shape as shown in FIG. 2, and has upper and lower openings 21.2.
A relatively thick cylindrical body portion 25 is provided between the dust cover and the dust cover so as to provide sufficient repulsive force when the dust cover is compressed in the axial direction.
ダストカバー２０の小開口部２１には補強環２３が一体
に埋設されていると共に、その補強環２３の径方向内周
位置に突条２４が形成されている。A reinforcing ring 23 is integrally embedded in the small opening 21 of the dust cover 20, and a protrusion 24 is formed at the inner peripheral position of the reinforcing ring 23 in the radial direction.
この突条２４は、ボールスタッド柄部１６の嵌着部１８
に形成された溝１９に飯台してボールスタッドと小開口
部との相対位置を決めるために形成されている。This protrusion 24 is connected to the fitting part 18 of the ball stud handle part 16.
The groove 19 is formed in the groove 19 to determine the relative position of the ball stud and the small opening.

）を適合さす端面２７が設けられている。The fitting part 18 for the dust cover small opening 21 formed in the handle part 16 of the pole stand 15 has a larger diameter than the other shaft parts, so that a connecting member (not shown) is attached to the immersed part side. An end face 27 is provided to accommodate the.
ダストカバー２０の小開口部２１には、その嵌着部１８
の頭部１７側の側面２８に係合してダストカバー２０の
反発力による復元を阻止する環状の***部２６が一体に
設けられている。The small opening 21 of the dust cover 20 has a fitting portion 18.
An annular raised portion 26 that engages with a side surface 28 on the head 17 side of the dust cover 20 to prevent the dust cover 20 from restoring due to repulsive force is integrally provided.
この***部２６は、ダストカバー小開口部２１を嵌着部
１８に嵌着させる際に、嵌着部外径に対して余剰のボリ
ュームを有する***内径側部分の内径拡大を容易にする
ため補強環の径方向内周から外れた位置に形成されてい
る。This raised portion 26 is reinforced to facilitate expansion of the inner diameter of the raised inner diameter side portion, which has an excess volume relative to the outer diameter of the fitted portion, when the dust cover small opening 21 is fitted into the fitting portion 18. It is formed at a position away from the radial inner circumference of the ring.

作業工数の増加も無い。Effects As described above, according to the present invention, the protrusion projecting in the inner circumferential direction on the socket side of the small opening separated from the radial inner circumference of the reinforcing ring comes into contact with the side surface of the ball stud fitting part. This prevents the dust cover from restoring due to the repulsive force, so the small opening in the dust cover can be installed without changing constraints such as space or stud swing angle. It is possible to prevent the ball stud from slipping out of the fitting part. Furthermore, since the reinforcing ring can be prevented from falling out of the small opening with the reinforcing ring buried in the small opening, the dust cover is easy to install and there is no increase in the number of steps for installing the dust cover.
