摘要： A strut mount includes an inner member, an outer member, and a body rubber. A stopper rubber which protrudes outward in an axial direction is disposed on the body rubber. The outer member includes a supporting portion which covers the stopper rubber from outside thereof in the axial direction. The stopper rubber includes a pedestal protrusion portion which protrudes outward in the axial direction from the inner member and a tip protrusion portion which protrudes outward in the axial direction from the pedestal protrusion portion, contacts the supporting portion, and has an elasticity in the axial direction lower than that of the pedestal protrusion portion. The pedestal protrusion portion and the tip protrusion portion taper outward in the axial direction.

摘要： A vibration-damping device (10) of the present invention includes a first attachment member (11), a second attachment member (12), an elastic body (13), and a partition member (16). In the partition member, a restriction passage (24) through which the first liquid chamber (14) and the second liquid chamber (15) communicate with each other is formed. The restriction passage includes a first communicating portion (26) which opens to the first liquid chamber, a second communicating portion (27) which opens to the second liquid chamber, and a main body flow passage (25) through which the first communicating portion and the second communicating portion communicate with each other. At least one of the first communicating portion and the second communicating portion includes a plurality of fine holes (26a) which are disposed in a flow passage direction of the main body flow passage. In plurality of fine holes, a flow passage length of a fine hole located apart from the other of the first communicating portion and the second communicating portion in the flow passage direction becomes longer.
