Abstract:
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 (C1) in communication with each other via first restricting passages (r1), and a second fluid chamber (C2) in communication with an auxiliary fluid chamber (C3) via a second restricting passage (r2). The first fluid chambers (C1) are disposed at opposite sides of the inner member (2). The second fluid chamber (C2) 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 (C1).
