PROBLEM TO BE SOLVED: To provide a cushion body for upper support having a new structure in which a spring constant in an axial direction can be set low.SOLUTION: This invention is a cushion body 10 for an upper support provided with a cylindrical elastic body 12 arranged under a pre-compressed state between opposing surfaces between a vehicle body panel 44 that is externally inserted to a piston rod 42 of a shock absorber and the piston rod 42 is inserted and passed and a fitting member 48 arranged at the piston rod 42. An inner diameter size of the cylindrical elastic body 12 is set to be larger than an outer diameter size of the piston rod 42, a peripheral approaching part 28 that is most nearly adjacent to the fitting member 48 under a pre-compression state at an axial end surface at the fitting member 48 for the cylindrical elastic body 12 is positioned at a more outer periphery than the minimum outer diameter part of the cylindrical elastic body 12.SELECTED DRAWING: Figure 1

    【課題】軸方向のばね定数を小さく設定することができる、新規な構造のアッパーサポート用のクッション体を提供すること。【解決手段】ショックアブソーバのピストンロッド42に外挿されて、ピストンロッド42が挿通される車体パネル44とピストンロッド42に設けられる取付部材48との対向面間に予圧縮された状態で配設される筒状弾性体12を備えたアッパーサポート用のクッション体10であって、筒状弾性体12の内径寸法がピストンロッド42の外径寸法よりも大きくされていると共に、筒状弾性体12の取付部材48側の軸方向端面において予圧縮前の状態で取付部材48に最も近接する周状近接部28が、筒状弾性体12の最小外径部分よりも外周に位置している。【選択図】図1
