A separation plate (45) of the disclosed antivibration device (1) is provided with an elastic material separation plate main body (46) held between a protruding section (60) and a support section (54), and a strengthening member (47) configured from a rigid body more rigid than the separation plate main body (46) and embedded inside the separation plate main body (46). The separation plate main body (46) separates a main liquid chamber (9A) and an auxiliary liquid chamber (9B) and seals the open end of the rigid member (50), and the space enclosed by the rigid member (50) and the separation plate main body (46) configures a restricted passage (10). Further, in the separation plate main body (46), a passage portion (42) passing along the axis direction and communicating between the main liquid chamber (9A) and the restricted passage (10) is formed, and the strengthening member (47) is arranged so as to surround the outer edge of the passage portion (42) in the separation plate main body (46). |
