Abstract

　筒部材（３）、取付部材（２）、筒部材（３）と取付部材（２）とを弾性的に連結すると共に筒部材（３）の一方の開口端を閉塞するゴム弾性体（４）、筒部材（３）の他方の開口端を閉塞するダイヤフラム（５）、及び、筒部材（３）内の液室（６）を主液室（６Ａ）と副液室（６Ｂ）に区画する仕切り部材（７）、を備える防振装置において，仕切り部材（７）は、オリフィス通路（８１）及び収容室（７６）を有するオリフィス部材（７０）と、オリフィス部材（７０）に被着される蓋体（７３）と、収容室（７６）内に収容されて主液室（６Ａ）の液圧変化に伴って動作する可動部材（７１）を備え、オリフィス部材（７０）に、蓋体（７３）の周壁部（７３ｃ）が圧入嵌合される被圧入部（８８）が収容室（７６）の周囲に形成され、オリフィス部材（７０）の端面に溝（７７）が形成され、溝（７７）の外側に設けられた外周部に被圧入部（８８）が形成され、溝（７７）の内側に設けられた内周部は外周部に対して離間される。
