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