First Claim
Patent Images
1. A thrust sliding bearing comprising:
- an annular upper case, into which an upper end portion of a piston rod is inserted is inserted, the piston rod being used in a shock absorber of a strut-type suspension;
an annular lower case overlapped with the upper case to be rotatable relative to the upper case about an axial center of the piston rod;
an annular synthetic resin-made sliding bearing piece provided in an annular space formed between the upper case and the lower case for receiving a thrust load of the piston rod; and
an annular metal plate attached to the piston rod and interposed between the upper case and the synthetic resin-made sliding bearing piece,wherein the upper case is integrally configured by an annular upper case base, which has an annular bottom surface, and by an upper case cylindrical portion, which is provided to extend vertically from the annular bottom surface of the upper case base to be fitted in the lower case, andwherein the synthetic resin-made sliding bearing piece is fixed to an inner side of the upper case cylindrical portion of the upper case.

Abstract
A thrust sliding bearing reduces the number of components to thereby reduce the burden of assembly and components management and prevents unusual wear of a surface of an annular synthetic resin-made sliding bearing piece, which faces an annular metal plate. A thrust sliding bearing comprises an upper case which is integrally formed at least by an annular upper case base having an annular bottom surface and by an upper case cylindrical portion which is provided vertically from the annular bottom surface of the upper case base to be fitted in a lower case, wherein a synthetic resin-made sliding bearing piece is fixed to the inner side of the upper case cylindrical portion.
