Document Type and Number:
WIPO Patent Application WO/2004/081408
Kind Code:
A1
Abstract:
A vibration-isolating apparatus where an orifice can be stably opened and closed is provided at reduced production costs. A plunger (236) for opening and closing an idle orifice (252) is positioned being fitted so as to be slidable against an inner wall face of an orifice-forming member (222). At the center of the plunger (236) is formed a shaft (262) extending downward. A projection, or a bearing (266), in which a through-hole that slidably fits on the shaft (262) is formed on the bottom face of the orifice-forming member (222). The shaft (262) and the bearing (266) together structure a guiding member for guiding the reciprocating motion of the plunger (236).
