Sliding bearing

A sliding bearing comprising an inner ring, an outer ring, and a sliding contact member interposed therebetween,

• wherein said inner ring has a curved outer circumferential surface formed along an outer circumference thereof and a shaft-receiving hole which fits on a supporting shaft along an inner circumference thereof;
• said sliding contact member is a molded body, made of a resin composition, which has a curved surface making sliding contact with said curved outer circumferential surface of said inner ring with said curved surface of said sliding contact member being opposed to said curved outer circumferential surface of said inner ring;
• said sliding contact member is fitted on said inner ring by an elastic deformation of said sliding contact member;
• and
• said outer ring does not contact said inner ring and holds said sliding contact member on an inner circumferential side thereof with said outer ring covering said sliding contact member,
• wherein said outer ring has an open portion formed on an axial one end surface thereof and a pawl portion formed at an edge of said open portion;
• and said sliding contact member is combined with said outer ring by inserting said sliding contact member into said outer ring from said open portion thereof and fixed by said pawl portion.

• wherein said curved outer circumferential surface of said inner ring is formed as a concave curved surface;
• and said curved surface of said sliding contact member is formed as a convex surface;
• and
• wherein a non-curved surface portion is formed along an entire circumference of a central portion of said convex curved surface of said sliding contact member in an axial direction thereof.
