To prevent a hard stopper part exposed due to abrasion of a stopper elastic part from colliding with an inner peripheral surface side of an external cylinder.SOLUTION: On an outer peripheral surface of an inside attachment member 11, a stopper part 16 is formed, which can contact with an inner peripheral surface side of an outer cylinder 12 when the inside attachment member and the outer cylinder relatively moves so as to approach each other. A stopper elastic part 34 covers the stopper part. At a circumferential intermediate portion in the stopper part, a recess part 16a is formed so as to extend radially inward in a recess axis direction. In the stopper elastic part, an outside portion 34b positioned outside in a circumferential direction with respect to an inside portion 34a covering the recess part of the stopper part, projects radially outward with respect to the inside portion.SELECTED DRAWING: Figure 1

    【課題】ストッパ弾性部の摩耗により露出した硬質のストッパ部が、外筒の内周面側に衝突するのを抑制する。【解決手段】内側取付部材11の外周面に、内側取付部材および外筒12が相対的に接近移動したときに、外筒の内周面側に当接可能なストッパ部16が形成され、ストッパ部を覆うストッパ弾性部34を備え、ストッパ部における周方向の中間部分に、径方向の内側に向けて窪み軸方向に延びる窪み部16aが形成され、ストッパ弾性部において、ストッパ部の窪み部を覆う内側部分34aより周方向の外側に位置する外側部分34bは、内側部分より径方向の外側に突出している。【選択図】図1
