To suppress the abutting of a sealing material on a member provided inside an outer cylinder.SOLUTION: Between an inside attaching member 11 and an outer cylinder 12, a coating member 17 is arranged, which covers a space between middle elastic bodies adjacent to each other in a circumferential direction from the outer side in a diametrical direction and defines a liquid chamber 14a between the inside attaching member and the coating member. An orifice passage communicating the liquid chambers is formed between the coating member and the outer cylinder. The coating member is formed with a first communication opening 18 and a second communication opening that communicate each liquid chamber and the orifice passage separately. An injection hole 12a formed on the outer cylinder and sealed by a sealing material 16 is opened toward at least one of the first communication opening and the second communication opening.SELECTED DRAWING: Figure 3

    【課題】封止材が、外筒の内側に設けられている部材に当接するのを抑制する。【解決手段】内側取付部材11と外筒12との間には、周方向で互いに隣り合う中弾性体同士の間を径方向の外側から覆い内側取付部材との間に液室14a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、被覆部材に、各液室とオリフィス通路とを各別に連通する第1連通開口18および第2連通開口が形成され、外筒に形成され、かつ封止材16に封止された注入孔12aは、第1連通開口および第2連通開口のうちの少なくとも一方に向けて開口している。【選択図】図3
