Kind Code:

A1

Abstract:

This anti-vibration device (1) comprises: an inner attachment member (11); an outer cylinder (12) that surrounds the inner attachment member; and elastic bodies (31, 32) that elastically connect the inner attachment member and the outer cylinder. The elastic bodies each comprise: a pair of end elastic bodies (31) fitted inside the outer cylinder; and a pair of central elastic bodies (32) arranged separately on both sides sandwiching the inner attachment member, between the end elastic bodies. A covering member (17) that demarcates liquid chambers (14a, 14b) from the inner attachment member is arranged between the inner attachment member and the outer cylinder. An orifice passage that communicates between the liquid chambers is formed between the covering member and the outer cylinder. The central elastic bodies are formed from a rubber material over the entire area thereof. The covering member surrounds the inner attachment member over the entire periphery from the radially outward side, and compressively deforms the central elastic bodies radially inward and circumferentially inward.
