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).
