Provided is a vibration damping device that reduces parts cost and improves productivity. The vibration damping device includes: a mounting member (10) that is attached to a vibration source; a holder (20) that is attached to a vibration receiver; and an insulator (30) that connects the mounting member (10) with the holder (20), wherein the holder (20) has a base portion (21) to which an end of the insulator (30) is coupled and a stopper portion (22) that rises from the base portion (21), and the insulator (30) has a pair of rubber feet (31 a, 31 b) that faces each other at a distance, wherein the pair of rubber feet (31a, 31 b) defines a cavity (35) therebetween, and the base portion (21) has an opening (25) formed therein at a position corresponding to the cavity (35).

A fluid-filled tubular vibration-damping device including: an inner shaft member and an outer tube member connected by a main rubber elastic body defining a non-compressible fluid filling region partitioned into two axially-opposite fluid chambers connected by an orifice passage, by a partition wall rubber fixed to a side of the inner shaft member in an inner periphery thereof and inserted in a side of the outer tube member at an outer periphery thereof so that the partition wall rubber is axially movable relative to the side of the outer tube member; a seal tubular part formed integrally at the outer periphery of the partition wall rubber to axially protrude to opposite sides; and a thicker annular fitting part formed integrally at each protruding tip of the seal tubular part, and fitted in the side of the outer tube member, slidably along it.

An antivibration device capable of securing a thickness dimension of a stopper rubber without changing a gap between a connecting member and a stopper wall portion. A connecting member includes a base surface and a receding surface located to recede beyond the base surface in a direction to go away from a stopper wall portion, the base surface and the receding surface face the stopper wall portion, and a stopper rubber includes an inner fitting portion at which the connecting member is internally fitted. Thus, it is possible to secure a thickness dimension of the stopper rubber without changing a gap between the connecting member and the stopper wall portion.

A transmission mount installed in a vehicle body in order to support the weight of a transmission includes a housing bracket including a housing having stopper-fixing holes and stopper-position-fixing portions, a stopper having insertion-protruding portions formed so as to be inserted into the stopper-position-fixing portions, fixing pieces formed so as to be inserted into the stopper-fixing holes and curled, and fixing holes formed near the fixing pieces, and an inner steel member having protruding pieces formed so as to be inserted into the fixing holes formed in the stopper. The stopper contacts a transmission bracket of a powertrain when a transmission of the powertrain is biased to the left in response to a right turn of a vehicle, thereby suppressing movement of the powertrain and further improving steering performance.

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.

A torque rod including: a rod member; and a rubber bushing provided at a lengthwise end of the rod member, wherein the rubber bushing includes an inner axial member, an outer tubular member, and a rubber elastic body connecting the inner axial member and the outer tubular member with each other, the lengthwise end of the rod member is fixed to the inner axial member of the rubber bushing constituted by a part separate from the rod member, and a stopper to limit a relative displacement amount of the inner axial member and the outer tubular member in the rubber bushing is constituted in contact sections of the rod member and the outer tubular member.

A transmission mount installed in a vehicle body in order to support the weight of a transmission includes a housing bracket including a housing having stopper-fixing holes and stopper-position-fixing portions, a stopper having insertion-protruding portions formed so as to be inserted into the stopper-position-fixing portions, fixing pieces formed so as to be inserted into the stopper-fixing holes and curled, and fixing holes formed near the fixing pieces, and an inner steel member having protruding pieces formed so as to be inserted into the fixing holes formed in the stopper. The stopper contacts a transmission bracket of a powertrain when a transmission of the powertrain is biased to the left in response to a right turn of a vehicle, thereby suppressing movement of the powertrain and further improving steering performance.

A roll rod device for a vehicle includes a mounting flange mounted to a vehicle body; a housing of a cylindrical shape integrally formed at the mounting flange; a roll rod having a first end coupled to the housing to be slid and moved and a second end on which a bush unit is mounted; and an attenuation unit mounted to the first end of the roll rod and attenuating a vibration and an impact force while being slid and moved, or being compressed and tensioned in an axis direction of the roll rod inside the housing.

A tubular vibration-damping device including: a vibration-damping device main unit wherein a main rubber elastic body is externally fixed to an inner shaft member; an outer tube member mounted on an outer peripheral face of the main unit; a pair of stopper protrusions protruding to opposite sides of a first axis-perpendicular direction at the inner shaft member; a cushion rubber layer fixed to the stopper protrusions; a stopper concavity provided in an inner peripheral face of the outer tube member to receive the stopper protrusions being inserted, with a wall opposed to the stopper protrusions in an axial direction, the first axis-perpendicular direction, and a second axis-perpendicular direction orthogonal thereto; and stoppers for all the directions constituted by contact of the wall and the stopper protrusions to limit relative displacement between the inner shaft member and the outer tube member.
