VIBRATION-DAMPING DEVICE

An anti-vibration device has excellent durability while reducing the amount of elastic deformation of an elastic body to a desired value. The disclosed anti-vibration device (1) includes an inner member (2), an outer member (3), an elastic body (4) that allows relative displacement between the inner member (2) and the outer member (3), a pair of first fluid chambers (C 1 ) in communication with each other via first restricting passages (r 1 ), and a second fluid chamber (C 2 ) in communication with an auxiliary fluid chamber (C 3 ) via a second restricting passage (r 2 ). The first fluid chambers (C 1 ) are disposed at opposite sides of the inner member (2). The second fluid chamber (C 2 ) is disposed in an orthogonal direction (Z) that is orthogonal to a sandwiching direction (Y) and to a direction along the axis (O) of the inner member (2). Stopper parts (S) are provided in the first fluid chambers (C 1 ).
