To improve the durability of a connecting part with an inside attaching member in an end elastic body.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 11 and the coating member. Between the coating member and the outer cylinder, an orifice passage communicating each liquid chamber is formed. The inside attaching member is equipped with a core metal portion 21 showing a non-circular shape in a plane view, and a resin portion 22 adhered to an outer peripheral surface of the core metal portion. In the inside attaching member, at least a partial outer peripheral surface of a part coupled with an end elastic body is located radially inside an outer peripheral surface of a part that is located axially inside the above-mentioned part.SELECTED DRAWING: Figure 2
【課題】端弾性体における内側取付部材との接続部分の耐久性を向上させる。【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11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、内側取付部材は、平面視で非円形状を呈する芯金部21と、芯金部の外周面に固着された樹脂部22と、を備え、内側取付部材において、端弾性体が連結された部分の少なくとも一部の外周面は、この部分より軸方向の内側に位置する部分の外周面より径方向の内側に位置している。【選択図】図2
