Abstract:
Provided is a vibration-damping device having a novel structure, the vibration-damping device being capable of effectively having desired dynamic spring properties and being configured so that a stopper member is stably retained in a receiving recess in a vibration-damping device body even before the mounting of the vibration-damping device on a vehicle, etc. The inner peripheral surface of a cylindrical section (24) which constitutes the peripheral wall of a receiving recess (30) comprises an elastic tapered section (46) which is provided with a contact surface (48) gradually sloped to the inner peripheral side toward the opening of the receiving recess (30). A stopper member (14) is provided with a stopper protrusion (40) which protrudes to the outside in the direction perpendicular to the axis. The stopper protrusion (40) is provided further inward of the receiving recess (30) than the elastic tapered section (46) of the receiving recess (30), and the stopper protrusion (40) is superposed on the elastic tapered section (46) when viewed in an axial projection.
