摘要： Provided is a sliding bushing in which sliding of an inner shaft member with respect to a main rubber elastic body is allowed. The inner shaft member includes a bulge part provided midway in an axial direction. A braided cloth-like sliding liner is arranged between the inner shaft member and the main rubber elastic body so as to be non-adhesive and slidable with respect to the inner shaft member. In a portion of the sliding liner arranged on an outer periphery with respect to a large diameter part of the bulge part of the inner shaft member, a coarse part is provided of coarser braid mesh than a portion of the sliding liner arranged on an outer periphery with respect to a small diameter part on both axial sides of the large diameter part.

摘要： A manufacturing method of a vibration damping bushing wherein an outer cylindrical member arranged on an outer peripheral side of an inner axial member is provided with on its both axial sides a pair of first inclined cylindrical parts each having a diameter gradually reduced toward an axial outside and a pair of second inclined cylindrical parts each extending further toward the axial outside from an axial end of the corresponding first inclined cylindrical part with an inclination angle smaller than that of the first inclined cylindrical part. The outer cylindrical member is arranged on the outer peripheral side of the inner axial member to be connected thereto by a main rubber elastic body. Axial ends of the main rubber elastic body are deformed by increasing the inclination angle of the second inclined cylindrical parts of the outer cylindrical member through a drawing operation.

摘要： In a vibration damping device applying a magnetic force from a magnetic field generation unit to an orifice path communicating with fluid chambers into which a magnetic functional fluid is filled and controlling vibration damping properties. An intermediate cylindrical member to which an outer cylindrical member formed by a non-magnetic material is externally fit and fixed is formed by a ferromagnetic material. In the intermediate cylindrical member, a magnetic field acting opening part is provided at a position corresponding to the orifice path.

摘要： Provided is a sliding bushing in which an inner shaft member and an outer tube member are connected by a main rubber elastic body and sliding of the inner shaft member with respect to the main rubber elastic body is allowed. The inner shaft member includes a bulge part of a large diameter provided midway in an axial direction. The outer tube member includes a tapered part whose diameter decreases axially outward at both axial end portions. An outer peripheral surface of the bulge part in the inner shaft member includes a non-adhesive part that is non-adhesive to the main rubber elastic body and is allowed to slide with respect to the main rubber elastic body, and an outer peripheral surface axially outside the non-adhesive part in the inner shaft member includes an adhesive part to which the main rubber elastic body is adhered by vulcanization.

摘要： A vehicle-use resin module including a strength member made of synthetic resin and including a mounting hole, and an attachment member attached to the mounting hole and configured to be subjected to an external force. The attachment member includes an outer fitting having a tubular part arranged in the mounting hole in an inserted state. The outer fitting includes an outer circumferential projection projecting to a radially outer side of the tubular part. The strength member is an insertion-molded component having a structure in which the outer circumferential projection of the outer fitting is embedded so as to be inserted inside a circumferential wall of the mounting hole. A surface of the tubular part of the outer fitting and a surface of the outer circumferential projection are each directly fixed to the strength member with an adhesive.
