加わっても該フランジ部10は剥がれにくい構造となる。In the above description, the outer cylinder 1 is arranged in the radial direction (B
Direction), stress is applied to the rubber cylinder 9 in this method (direction B), but this stress is mainly applied to the inner peripheral surface 9d of the rubber cylinder 9, and the flange portions 10 and 10 are affected. Almost no force is applied. When the outer cylinder 1 is displaced with respect to the inner cylinder 3 in the axial direction (C direction), stress is applied to the rubber cylinder 9 in this method (C direction), and this stress is mainly caused by the flange portion 10. Also, the flange portion 10 is barely covered by the inner portion 9e. Particularly in this embodiment, the thickness d 1 of the flange portion 10 is much thinner than the thickness d 2 of the inner portion 9e of the flange portion 10, so that the effect is remarkable. Since the flange portion 10 fits into the step portion 7, the end surface of the tip end of the flange portion 10 abuts on the vertical surface of the step portion 7, and the flange portion 10 is axially supported by the vertical surface, and the flange portion 10 Even if a force is applied to the flange 10, the flange 10 has a structure that does not easily come off.

フランジ部は剥がれにくい構造となる。(Effect of the Invention) Since the inner part of the rubber cylinder is fitted into the recess of the outer circumference of the inner cylinder, and the flange part is fitted into the stepped part of the inner cylinder, the inner cylinder and the outer cylinder are fixed. Even if the flange portion is displaced in the axial direction, almost no stress is applied to the flange portion. Therefore, it is possible to prevent the peeling between the inner cylinder and the rubber cylinder starting from this portion. Since the flange portion fits into the step portion, the end surface of the tip of the flange portion abuts the vertical surface of the step portion, and the flange portion is axially supported by the vertical surface, and even if force is applied to the flange portion. The flange portion has a structure that does not easily peel off.
