A stopper includes: a mounting hole into which an inside member is inserted; and a plurality of surface ribs and a plurality of rear surface ribs. A plurality of surface ribs respectively protrude from the surface and linearly disposed. A plurality of the rear surface ribs, on a rear surface, respectively protrude from between the surface ribs and linearly disposed. In a predetermined region in a circumferential direction of the mounting hole, intervals between the surface ribs adjacent to each other and intervals between the rear surface ribs adjacent to each other are set to be constant throughout an entire length in an extending direction in which the surface ribs and the rear surface ribs extend.

An assembly bearing for a motor vehicle assembly includes an inner part, an elastomer supporting body in which the inner part is embedded, and an outer part that surrounds the supporting body. In embodiments, the outer part includes a first part and a second part that are clipped to at least one fastening element connected to the supporting body.

A vibration-damping device comprising: first and second attachment members connected elastically by a main rubber elastic body; an inner bracket fixed to the first attachment member with its basal end superposed on an outside end face of the first attachment member while extending laterally relative to the first attachment member; a bag-shaped stopper rubber mounted covering the basal end of the inner bracket in a non-adhesive way; a through hole formed in the stopper rubber so that the first attachment member inserted through it and the inner bracket are mutually fixed; and an elastic contact part provided at a rim of the through hole and pressed against an outer peripheral face of the first attachment member from a distal end side of the inner bracket so that the stopper rubber is positioned relative to the inner bracket in extension direction of the inner bracket.

A unit bearing includes a bearing body configured to be received by a rigid bearing housing provided with an opening on at least one side, a carrier element and at least one support member engaging the rigid bearing housing through the opening. The bearing body includes elastomer abutments. The elastomer abutments are disposed between the rigid bearing housing and the support member. The carrier element is disposed between the support member and the elastomer abutments. The unit bearing is configured such that relative movements of the bearing body with respect to the bearing housing caused by loading of the support member along three mutually orthogonal directions are limited by the elastomer abutments.

An elastomer bearing includes a support block, a carrier, a bearing element, a stop damper, and an elastomer body. The bearing element is attached to the support block. The elastomer body connects the carrier to the bearing element. The support block and the carrier, as viewed in an axial direction of the bearing element, engage with one another with play. The stop damper is arranged in the region of the interface between the support block and the carrier. The stop damper limits a maximum displacement of the support block and the carrier, relative to one another both in a radial direction and in an axial direction.

A junction with an antivibration base body joined to its outer periphery is equipped with a chamfer portion where a corner connecting a flange portion to the junction is removed, a base portion connected to the chamfer portion in the axial direction, and an end portion connected to the base portion in the axial direction. At the base portion, a first projection plane made by being projected in a first direction orthogonal to the axis is substantially the same in area as a second projection plane made by being projected in a second direction orthogonal to the axis and the first direction. At the end portion, the area of the second projection plane is set to be larger than the area of the first projection plane.

An engine mount may include: a support device; a bracket device; and a vibration proof device which connects the support device and the bracket device, and, in which the vibration proof device may include a nozzle device fastened to the support device, and has a nozzle plate dividing an internal space of the vibration proof device into a first liquid chamber and a second liquid chamber, and a flow path penetrating the nozzle plate; a first insulator defining the first liquid chamber together with the nozzle plate; a first core protruding from the first insulator toward one side, and fastened to the bracket device; a second insulator defining the second liquid chamber together with the nozzle plate; and a second core protruding from the second insulator and fastened to the bracket device.

An engine mount apparatus may include a mount housing which has an internal space; a partition device which partitions the internal space into an upper space and a lower space; a nozzle plate which is provided in the upper space and allows a fluid to selectively pass through the nozzle plate; an upper diaphragm which is fastened to an upper surface of the nozzle plate and defines an upper liquid chamber; a core which penetrates the partition device, and has an upper portion disposed in the upper space, and a lower portion disposed in the lower space; a lower diaphragm which extends from the upper portion of the core to a lower surface of the nozzle plate, and defines a lower liquid chamber; and a rubber member which is provided in the upper space, and connects the upper portion of the core and the partition device.

An engine mount for a vehicle, in which of the inside of the engine mount is divided into an upper chamber and a lower chamber by an orifice plate, and an encapsulated hydraulic liquid flows through a center hole provided at the center of the orifice plate in accordance with a change in volume of the upper chamber, is provided. The engine mount is configured to include: a coil which is mounted in the orifice plate and forms a magnetic field in the center hole as electric current is applied; and a drive device which is formed to have a diameter corresponding to a diameter of the center hole, is configured to be inserted and disposed into the center hole, and selectively closes the center hole by moving upwards or downwards in the center hole by the formed magnetic field.
