<p>A fluid filled type vibration damping device (10, 92) including: a main rubber elastic body (16) connecting first and second mounting members (12, 14); a pressure-receiving chamber (60) and an equilibrium chamber (62) situated to either side of a partition member (44) with a non-compressible fluid filled therein; an orifice passage (68) through which the two chambers (60, 62) communicate with one another; a moveable rubber plate (72, 96) installed on the partition member (44); and a constraining plate (74, 98) affixed to the moveable rubber plate (72, 96). The constraining plate (74, 98) has at least one penetrating window (84) such that the moveable rubber plate (72, 96) closes off the penetrating window (84). A slit (86) is formed in the moveable rubber plate (72, 96) in the section thereof that closes off the penetrating window (84). The slit (86) will open up through elastic deformation of the moveable rubber plate (72, 96), and short circuit the pressure-receiving chamber (60) and the equilibrium chamber (62), thereby constituting a short circuiting mechanism.</p> |
