Abstract
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.
Claims8
A sliding bushing, having a structure 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, wherein
- the inner shaft member comprises a bulge part provided midway in an axial direction;
- a braided cloth 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;
- and
- wherein the braided cloth sliding liner comprises:
- a coarse part, arranged on an outer periphery with respect to a large diameter part of the bulge part of the inner shaft member;
- and
- a fine part, arranged on an outer periphery with respect to a small diameter part on both axial sides of the large diameter part,
- wherein a stitch or weave of the coarse part has a coarse braid mesh, and a stitch or weave of the fine part has a fine braid mesh,
- wherein a size of the coarse braid mesh of the coarse part is larger than a size of the fine braid mesh of the fine part.
