The body mount further includes a hydraulic damping system disposed between the first support surface and the second support surface, a washer and a travel-limiting cup joined to the cup portion of the second support member. The travel-limiting cup surrounds the washer and includes a compressible limiting member that limits axial movement of the inner tube when the washer contacts the compressible limiting member.

A hydraulic body mount includes a first support member that defines a first support surface that is adapted to engage the body of a vehicle and a second support member that defines a second support surface that is adapted to engage the frame of the vehicle. The hydraulic body mount includes a hydraulic damping system disposed between the first support surface and the second support surface and a travel-limiting cup disposed outside of the region between the first support surface and the second support surface. The travel-limiting cup includes an elastomeric limiting member adapted to limit the travel of the first support surface relative to the second support surface.

Anti-vibration mount comprising a first frame, a second frame, an elastomeric main body connecting the first frame and the second frame, the elastomeric main body allowing relative displacements of the second frame relative to the first frame in a first direction of vibration and in a second direction of vibration perpendicular to the first direction of vibration, the elastomeric main body also being suitable for mounting a weight in the first direction of vibration. An inertia body is connected to the first frame by an elastic suspension interposed between the inertia body and the first frame along the second direction of vibration. An elastomeric lateral abutment body is interposed between the first frame and the inertia body to limit the relative displacements of the second frame with respect to the first frame in the second direction of vibration. The inertia body has a natural frequency lower than 800 Hz.

A vibration proofing device (10) includes an insulator (50) interposed between a first attaching member (30) and a second attaching member (40), and is disposed in an internal space (95) of a second bracket (90). The first attaching member (30) is formed to have two side walls (33, 33) parallel to each other to face the inner face of the second bracket (90). The second attaching member (40) is a tubular member having an opening (41a) passing therethrough in an upper-lower direction. At least one of side edge portions of each side wall (33) is disposed outside the opening (41a) of the second attaching member (40). Each side wall (33) is provided on an outer face thereof with a stopper (51) made of an elastic material. With this configuration, it is possible to sufficiently absorb an impact shock resulting from the stopper (51) hitting the second bracket (90).

A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.

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.

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 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 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.

A liquid-sealed antivibration device is equipped with a shaft member and a sleeve member, an antivibration base body constituted by a rubber-like elastic body which elastically supports the sleeve member relative to the shaft member and which defines a first liquid chamber and a second liquid chamber between the shaft member and the sleeve member, and an orifice forming member made of a synthetic resin and disposed inside the sleeve member. The orifice forming member is formed with end surfaces on which a hole portion piercing along the axis of the shaft member opens, and an outer peripheral surface adhered closely to the sleeve member to form a groove portion becoming an orifice which makes the first liquid chamber communicate with the second liquid chamber, and recesses formed at corner portions defined by the end surfaces and the outer peripheral surface are connected to the hole portion.
