In a vibration damping device (1), a covering member (17) is disposed between an inner attachment member (11) and an outer cylinder (12), the covering member (17) covers a pair of middle elastic bodies (32) adjacent to each other in the circumferential direction from the outside in the radial direction, and a pair of liquid chambers (14a, 14b) are defined between the covering member (17) and the inner attachment member. A hole passage (19) for communicating each of the pair of liquid chambers with each other is formed between the covering member and the outer cylinder, and a first communication opening (18) and a second communication opening (20) for communicating each of the pair of liquid chambers with the hole passage are formed in the covering member. An injection hole (12a) formed in the outer cylinder and sealed by a seal (16) opens toward at least one of the first communication opening and the second communication opening.

    一种隔振装置(1),其中,在内侧安装构件(11)与外筒(12)之间配置有包覆构件(17),该包覆构件(17)从径向的外侧覆盖于沿着周向彼此相邻的一对中弹性体(32)彼此之间,在该包覆构件(17)与内侧安装构件之间划分形成一对液室(14a、14b),在包覆构件与外筒之间形成有使一对液室的各液室彼此连通的孔通路(19),在包覆构件形成有使一对液室的各液室和孔通路分别连通的第1连通开口(18)和第2连通开口(20),形成于外筒并且由密封件(16)密封的注入孔(12a)朝向第1连通开口和第2连通开口中的至少一者开口。
