PURPOSE:To ensure a limit passage, being long enough to allow for the flow of liquid, between an outer peripheral wall, extending to the outer periphery of a partition along a surrounding wall, and the surrounding wall, by a method wherein a partition is mounted to either a vibration generating part or a vibration collecting part and the surrounding wall is attached to the one or the other of them. CONSTITUTION:A cylindrical outer peripheral wall 39, having a given axial length, is secured to the outer periphery of a partition 38, the inner peripheral part, positioned facing the outer peripheral wall 39 of the partition 38, of a cylinder bracket 28 forms a surrounding wall, and a space between the surrounding wall and the outer peripheral wall 39 forms an orifice being a limit passage. Thus, a liquid chamber 26 is divided into an upper liquid chamber 26A and a lower liquid chamber 26B by means of the partition 38, and the upper liquid chamber 26A and the lower liquid chamber 26B are intercommunicated through an orifice 42 having a sufficient length, and this constitution provides an increased vibration absorbing effect. |
