Abstract:
1. A fluid-filled cylindrical vibration damping device comprising: an inner shaft member; an outer sleeve member disposed about the inner shaft member; a rubber elastic body elastically connecting the inner shaft member and the outer sleeve member; a fluid-sealing region formed between the inner shaft member and the outer sleeve member, and having a non-compressible fluid sealed therein; a stop rubber member disposed within the fluid-sealing region and projecting from one of the inner shaft member and the outer sleeve member toward an other of the inner shaft member and the outer sleeve member; and a rigid restricting member bonded on a projecting end portion of the stop rubber member, wherein the vibration damping device exhibits a vibration damping effect based on flow action of the non-compressible fluid flowing within the fluid sealing region during vibration input, wherein a part of the stop rubber member extends across the rigid restricting member so as to form an abutment rubber situated on and projecting from an outer peripheral portion of a front surface of the rigid restricting member so that the projecting end portion of the stop rubber member is brought into abutting contact with the other of the inner shaft member and the outer sleeve member with the abutment rubber, and wherein the inner shaft member includes at one axial end portion thereof an inner-side slant portion projecting diagonally outward in a diametric direction of the inner shaft member, and the outer sleeve member includes at a corresponding axial end portion thereof an outer-side slant portion projecting diagonally outward in a diametric direction of the outer sleeve member, axially opposed to the inner-side slant portion and with a spacing therebetween, and elastically connected to the inner-side slant portion via a toe correction rubber elastic member interposed therebetween.
