A dust cover assembly including: a dust cover made of resin and having a bellows tube portion; and an upper insulator made of rubber attached to a top end of the dust cover. An engaging tube portion is integrally formed with an upper part of the bellows tube portion of the dust cover. At least one engaging groove opens onto an outer peripheral face of the engaging tube portion and extends in a circumferential direction. At least one locking protrusion is formed on an inner peripheral face of the upper insulator having an annular shape and protrudes toward an inner peripheral side, while extending in the circumferential direction. The engaging tube portion of the dust cover is inserted into the upper insulator, while the locking protrusion is inserted into the engaging groove and is locked therein in an axial direction.

Dust cover assembly

Semi-tubular portions of two partition members partitioning a bushing body into an outer rubber portion and an inner rubber portion are asymmetrically arranged with respect to a reference plane containing a central axis of the bushing body and parallel to two attachment surfaces of a bracket. In addition, each of the semi-tubular portions is configured to have a length equal to or larger than a diameter of a stabilizer bar, the length being from one end to the other end in a circumferential direction of the semi-tubular portion in a projection view obtained by projecting the semi-tubular portion to a horizontal surface in a vertical direction.

Stabilizer bushing for vehicle and method of producing the same

A stabilizer bushing is provided which effectively reduces a torsional friction between a bushing body and a stabilizer bar. The stabilizer bushing includes a bushing bodymade of a tubular elastic body, a sliding memberfixed to an inner circumferential surface of the tubular elastic body, and two partition membersembedded in and bonded to a radially middle area of the bushing body. The partition membersdivide the bushing bodyinto an inner rubber portionthat is thin enough not to be elastically-deformed by a load applied thereto and an outer rubber portionthat is thicker than the inner rubber portion. Further, each of the partition membersincludes through holesthat are located so as to divide the partition member into a plurality of sections both in the axial and circumferential directions.

Stabilizer bushing for vehicle

A bump stopper for elastically limiting an amount of operation of a suspension system of a vehicle, including a rigid holding member which includes a hollow holding portion opening toward the other suspension member, a spring member which is formed of a foamed elastic material and which includes a base end portion held by the hollow holding portion of the holding member and also includes a free end portion projecting away from the holding portion toward the other suspension member, and a stopper rubber which projects from an end surface of the hollow holding portion of the holding member toward the other suspension member such that a free end surface of the stopper rubber is more distant from the other suspension member than a free end surface of the spring member.
