Vibration-damping device

摘要

A vibration-damping device includes a housing member and a pillar-shaped mass member housed within an accommodation space of the housing member with a slight spacing therebetween so that the mass member is freely displaceable within the accommodation space to come into impact on the housing member. A rubber buffer and an abutting rubber member integrally formed with each other and fixed to at least one of axial end portions of the mass member such that the rubber buffer covers an outer circumferential surface of the end portion of the mass member, and the abutting rubber member disposed over an end face of the axial end portion of the mass member. A void is formed between the abutting rubber member and the end portion of the mass member so that the abutting rubber member undergoes shear deformation upon an impact of the mass member on the housing member at the abutting rubber member.
