Abstract: An anti-vibration device (1) includes a covering member (17), arranged between an inner attachment member (11) and an outer cylinder (12), that covers, from outside in the radial direction, the area between a pair of middle elastic bodies (32) adjacent to each other in the circumferential direction, and defines a pair of liquid chambers (14a, 14b) between the inner attachment member and the covering member. An orifice passage (19) connecting each liquid chamber is formed between the covering member and the outer cylinder. A first connecting aperture (18) and a second connecting aperture (20) that separately connect each liquid chamber and the orifice passage are formed in the covering member. An injection hole (12a) formed in the outer cylinder and sealed by a sealing material (16) opens toward at least one of the first connecting aperture and the second connecting aperture.

Abstract: An outer attachment member (111) includes a first end member (117), a second end member (118), and an intermediate member (116), in which the first end member (117) and the second end member (118) are respectively fitted into both end portions of the intermediate member (116) in the axial direction, a coupled portion (135) provided in any one of the vibration generating part and the vibration receiving part is disposed on one end surface of both end surfaces of the first mounting projecting portion (124) in the axial direction provided in the intermediate member (116), and a second mounting projecting portion (125) is disposed on the other end surface thereof, the first mounting projecting portion (124) and the second mounting projecting portion (125) are separately provided with insertion holes (111a) through which fixing bolts (136) for integrally fixing the first mounting projecting portion (124) and the second mounting projecting portion (125) and for coupling the first mounting projecting portion (124) t
