CENTRIFUGAL-PENDULUM VIBRATION ABSORBING DEVICE

摘要

A cushioning member between plate bodies of a mass body and at end portions, in the circumferential direction, so as not to rotate relative to the plate bodies. The peripheral edges, on both sides in the width direction, of the outer peripheral surfaces of the cushioning member's first and second side portions abutting against a support member, along with swing of the mass body, are chamfered, reducing the possibility that the cushioning member enters in a clearance between the side surfaces of the support member and the plate bodies when the cushioning members' first side portion and the support member abut, or when the cushioning member's second side portion and the support member abut, along with swing of the mass body, suppressing damage to the cushioning member.

主权项

1. A centrifugal-pendulum vibration absorbing device comprising:
a support member attached to a rotary element; and a plurality of mass bodies each swingably supported by the support member and disposed adjacent to each other in a circumferential direction, wherein: the mass bodies each includes two plate bodies coupled to face each other via the support member; a cushioning member is attached between the two plate bodies; the cushioning member includes a first abutment portion that abuts against the support member along with swing of each of the mass bodies; and peripheral edges, on both sides in a coupling direction of the two plate bodies, of the first abutment portion of the cushioning member are chamfered.
