SLIDE BEARING CONSTRUCTION

PROBLEM TO BE SOLVED: To provide a slide bearing structure capable of having sliding resistance at a desired range in spite of dimensional tolerance in a specific range in the slide bearing structure wherein a cylindrical outer member and a cylindrical inner member are fitted with an interference fit via a bearing bushing. SOLUTION: The slide bearing structure 1 includes the outer member 2, an inner shaft member 3 arranged in the outer member 2, and the bearing bushing 7 intervened between the outer member 2 and the inner shaft member 3. The inner shaft member 3 is fitted to an inner peripheral surface 4 of the outer member 2 with an interference fit via the bearing bushing 7, individual sliding surfaces of an inner peripheral surface 6 of the bearing bushing 7 and an outer peripheral surface 5 of the inner shaft member 3 are formed of a synthetic resin, and the synthetic resin for forming both sliding surfaces is a combination wherein frictional torque between both sliding surfaces under pressurization based on the interference fit is within a designated range.
