PROBLEM TO BE SOLVED: To provide a vibration-proof device which suppresses vibration transmission in a vehicle vertical direction when a stopper part is actuated, and stabilizes a posture of a mounting device.SOLUTION: A stopper part 50 constituted from a rubber-like elastic body is interposed between a first regulation part 31 and a bracket member 20. The stopper part 50 has a projection part 52 which is disposed at an end of one side of a leg part 51 in a vehicle longitudinal direction, and the projection part 52 projects from the end to the one side in the vehicle longitudinal direction and to both sides in a vehicle vertical direction. Two bored parts 54 are formed that are open respectively to both sides in the vehicle vertical direction and that have a bottom with a depth reaching the leg part 51. When the stopper part 50 is actuated, the leg part 51 mainly undergoes shear deformation with respect to vibration input in the vehicle vertical direction, and therefore vibration transmission in the vehicle vertical direction is suppressed. Further, a posture of a mounting device 10 is stabilized when the two bored parts 54 collapse.

    【課題】ストッパ部が作動したときの車両上下方向の振動伝達を抑制できると共に、マウント装置の姿勢を安定化できる防振装置を提供すること。【解決手段】ゴム状弾性体から構成されるストッパ部50は、第1規制部31とブラケット部材20との間に介設される。ストッパ部50は、脚部51の車両前後方向一方側の端部に突出部52が設けられ、突出部52は、端部から車両前後方向一方側および車両上下方向両側へ突出する。車両上下方向両側にそれぞれ開口し脚部51に達する深さの有底の2つのすぐり部54が形成される。ストッパ部50が作動すると、車両上下方向の振動入力に対して脚部51はせん断変形が主体となるので、車両上下方向の振動伝達を抑制できる。また、2つのすぐり部54が潰れるときのマウント装置10の姿勢を安定化できる。【選択図】図2
