Abstract
Disclosed is a process for manufacturing a sintered slide bearing. A sintered porous bearing body is prepared from a powdered metal material and a resin material in a fluidable state is penetrated into the sintered porous bearing body. The resin material in the sintered porous bearing body is hardened, and the sintered porous bearing body after the hardening of the resin material is repressed to reduce a gap produced between the sintered porous bearing body and the hardened resin material by volume reduction caused on the resin material at the hardening.
