Claims

[Claims for Utility Model Registration] A bushing assembly that is interposed between a pivot shaft and a cylindrical member constituting a vibration transmission system and connects them in a vibration-proof manner, the bushing assembly having a spherical shape on the outer peripheral surface of an axially intermediate portion. an inner cylindrical metal fitting having a convex surface through which the pivot shaft is inserted; a cylindrical race fitting concentrically arranged at a predetermined distance on the outside of the inner cylindrical metal fitting; It has a spherical concave surface corresponding to the spherical convex surface, and is slidably fitted on the spherical concave surface to the spherical convex surface of the inner cylindrical fitting, while its outer circumferential surface is fitted into the inner circumferential surface of the axially intermediate portion of the race fitting. a pair of presser sleeves that are respectively fitted into both axial ends of the race fitting to firmly clamp the slider member in the direction of the bush axis; It has a radial protrusion that is continuous in the circumferential direction on the inner circumferential surface, and an axial protrusion that is continuous in the circumferential direction and protrudes axially outward from the end face of the presser sleeve in the axial direction. death,
a pair of sealing members integrally fixed to each presser sleeve; and a cylindrical member disposed outside the race fitting to elastically hold the race fitting against the cylindrical member. an elastic member, and the annular gap between the pair of presser sleeves and the inner cylindrical fitting is closed by the radial protrusion of the pair of sealing members abutting against the inner cylindrical fitting. and the pair of seals of the seal fitting are pressed into both axially end portions of the race fitting or both axially end portions of the race fitting such that a gap between the pair of presser sleeves and the race fitting is press-fitted into both axially end portions of the race fitting. 1. A spherical sliding bushing assembly, characterized in that the bushing assembly is configured such that the members are respectively closed by coming into contact with the axial protrusions.
