Abstract
A fluid-filled type vibration damping device including an elastic movable member attached to a partition member. The elastic movable member includes a clasped portion clasped by the partition member and a switching portion provided to an outer peripheral side of the clasped portion and positioned within a second orifice passage. An abutting portion is provided to the switching portion and projects to lengthwise opposite sides of the orifice passage. A switching mechanism is constituted for opening the orifice passage through a gap formed between the switching portion and the inside face of the orifice passage while closing the orifice passage by abutment of the abutting portion against the inside face of the orifice passage by means of a tilting motion of the switching portion relative to the clasped portion through elastic deformation of a thin portion provided between the clasped portion and the switching portion.
