To securely fix a coating member to an outer cylinder.SOLUTION: Between an inside attaching member 11 and an outer cylinder 12, between a pair of end elastic bodies 31, a coating member 17 is arranged which covers a part located between middle elastic bodies 32 adjacent to each other in a circumferential direction from outside in a diametrical direction and defines a liquid chamber 14b between the inside attaching member and the coating member. Between the coating member and the outer cylinder, an orifice passage communicating each liquid chamber is formed. The end elastic body is provided with an annular rigid body plate 33 extending in a circumferential direction. Either one end portion of both end portions in an axial direction of the coating member and the rigid body plate are axially sandwiched and fixed by a fixing portion 23 formed at either one end portion of both end portions in an axial direction of the outer cylinder.SELECTED DRAWING: Figure 2
【課題】被覆部材を外筒に対して強く固定する。【解決手段】内側取付部材11と外筒12との間には、一対の端弾性体31同士の間において、周方向で互いに隣り合う中弾性体32同士の間に位置する部分を、径方向の外側から覆い内側取付部材との間に液室14bを画成する被覆部材17が配設され、被覆部材と外筒との間に、各液室同士を連通するオリフィス通路が形成され、端弾性体に、周方向に延びる環状の剛体板33が設けられ、被覆部材の軸方向の両端部のうちのいずれか一方の端部、および剛体板は、外筒の軸方向の両端部のうちのいずれか一方の端部に形成された固定部23によって軸方向に挟まれて固定されている。【選択図】図2
