To provide a strut mount which can lower a dynamic spring constant at small amplitude vibration while raising a stationary spring constant at large amplitude vibration, in a vibration isolation base body whose each part is constituted of the same elastic body.SOLUTION: In a strut mount having an inside member, an outside member and an annular vibration isolation base body, either of the inside member or the outside member comprises a pair of annular stopper face parts for gripping the vibration isolation base body in mutual opposing directions. The other of the inside member or the outside member comprises a plate part which is gripped between a pair of the stopper face parts via the vibration isolation base body. The vibration isolation base body comprises a plurality of first salient parts and second salient parts which protrude to the stopper face part sides from the plate part side, and are dispersedly arranged in a peripheral direction. The first salient parts are pre-compressed between the plate part and the stopper face parts. A clearance of 0.05 to 0.5 mm exists between the second salient parts and the stopper face parts.SELECTED DRAWING: Figure 1

    【課題】各部が同一の弾性体から構成される防振基体において大振幅振動時の静ばね定数を高くしつつ、小振幅振動時の動ばね定数を低くできるストラットマウントを提供すること。【解決手段】内側部材と、外側部材と、環状の防振基体とを備えるストラットマウントであって、内側部材または外側部材の一方は、互いの対向方向に防振基体を挟む一対の環状のストッパ面部を備える。内側部材または外側部材の他方は、一対のストッパ面部の間に防振基体を介して挟まれる板部を備える。防振基体は、板部側からストッパ面部側へ突出して周方向に分散配置される複数の第1突出部および第2突出部を備える。第1突出部は、板部とストッパ面部との間で予圧縮される。第2突出部とストッパ面部との間に0.05~0.5mmの隙間がある。【選択図】図1
