摘要： A torque rod for straddling connection target members including a rod member and a rubber bushing provided to a lengthwise end of the rod member. The rubber bushing includes an inside shaft member, an outer peripheral member to be attached to one of the connection target members, and a rubber elastic body connecting the inside shaft member and the outer peripheral member. The rubber bushing is a part separate from the rod member and the end of the rod member is fixed to the inside shaft member. The rod member includes an abutting face to abut against the one of the connection target members without interposing the outer peripheral member of the rubber bushing. A stopper to limit an amount of elastic deformation of the rubber elastic body in the rubber bushing is constituted by including the abutting face of the rod member.

摘要： A vibration damping device including: a first mounting member including a fitting tube part opening to a side for fitting and mounting of an inner bracket; a second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; and a stopper rubber provided on a portion of a circumference of the fitting tube part while projecting to the side from an opening end surface of the fitting tube part, the stopper rubber being configured to overlap the inner bracket. The stopper rubber is configured to be elastically deformed by fitting and mounting of the inner bracket into the fitting tube part so as to abut and overlap the inner bracket in a state urged by an elasticity of the stopper rubber itself.

摘要： A tubular vibration-damping device including: an inner shaft member; an outer tube member; a main rubber elastic body elastically connecting the inner shaft member and the outer tube member, the main rubber elastic body being penetrated by a through hole in an axial direction; and a stopper rubber separated from the main rubber elastic body, the stopper rubber including an insert that is inserted in the through hole. A gap is provided in an axially middle portion of the insert, and the insert includes axially opposed faces that are opposed to each other in the axial direction with the gap in between.

摘要： A fluid-filled vibration damping device including an inner member, an outer member having a tubular part whose radially inner surface has a quadrangular tube shape, a main rubber elastic body elastically connecting the two members, and a partition having a quadrangular plate shape disposed on a radially inner side of the tubular part. An outer peripheral surface of an axial end of the main rubber elastic body is anchored to the radially inner surface of the tubular part. An annular sealing rubber pressed against an outer peripheral edge of an axial end face of the partition is provided to the axial end of the main rubber elastic body. An axis-perpendicular inside dimension and a width dimension of the sealing rubber are made larger in a diagonal direction of the radially inner surface of the tubular part than in an opposite side direction thereof.

摘要： A fluid-filled vibration-damping device including two chambers partitioned by a partition member and mutually communicated by an orifice passage and a communication passage which is provided at the partition member, with a movable rubber film disposed in the communication passage so that each pressure of the chambers is applied to the respective face of the movable rubber film, wherein the movable rubber film includes a thick-walled outer peripheral retaining part formed at its outer rim and clamped by the partition member and reinforcing crosspieces projecting on its face and extending inward from the outer peripheral retaining part to mutually intersect, and a width dimension of at least one of the reinforcing crosspieces is made small in a vicinity of the intersection part to provide a narrow part by which the movable rubber film has a low-spring area in the vicinity of the intersection part.
