摘要： A vibration isolator which is capable of stably opening and closing an orifice is provided at low manufacturing cost. A plunger for opening and closing an idle orifice is disposed in a manner that is slidably engaged with the inner wall surface of an orifice-forming member. A shaft portion extending downward is formed in the central portion of the plunger. A convex portion which is formed with a through-hole in which the shaft portion is slidably is provided on the bottom of the orifice-forming member so as to provide a bearing portion. The shaft portion of the plunger and the bearing portion of the orifice-forming member constitute a guide member for guiding the reciprocating motion of this plunger.
