A liquid seal bushing includes an outer member, an inner member, and an elastic body which connects the outer member and the inner member to each other. The bushing includes two liquid chambers, a connection path which connects the two liquid chambers and extends in one direction, a first communication path which allows communication between one end portion of both end portions of the connection path, the one end portion being located on a side of one liquid chamber of the two liquid chambers, and the other liquid chamber, a second communication path which allows communication between the other end portion of the both end portions of the connection path, and a linear motor provided inside the outer member including a movable element in the connection path and movable in the one direction to closes both openings of the first communication path and the second communication path.

Liquid seal bushing

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.

Strut mount

A toe correction bushing including: an inner cylinder; a tubular damping mechanism which surrounds the inner cylinder; a retaining cylinder which surrounds the damping mechanism; an outer cylinder which surrounds the retaining cylinder; and an outer elastic body which connects the outer cylinder and the retaining cylinder. The retaining cylinder includes a bottom plate portion which extends inward in a radial direction from an end portion of the retaining cylinder on one side of an axial direction and a crimped portion which is located at an end portion on the other side of the axial direction and is crimped on the inside of the radial direction. The outer cylinder includes a facing surface which faces the one side of the axial direction and faces a part of a vehicle body. The facing surface is provided with a cushioning elastic body.

Toe correction bushing and rear suspension device

The active damper upper mount includes an inner member () to which an upper end portion of a rod () of an active damper () is fixed, an intermediate member () that surrounds the inner member in a circumferential direction around a rod axis (O, O), an outer member () that surrounds the intermediate member in the circumferential direction and is attached to a vehicle body side, a first elastic body () that is disposed between the inner member and the intermediate member and supports the inner member and the intermediate member so as to be elastically displaceable relative to each other, and a second elastic body () that is disposed between the intermediate member and the outer member and supports the intermediate member and the outer member so as to be elastically displaceable relative to each other.
