Abstract:
A method of manufacturing sliding bearings, having:a first member provided with a sliding guide surface, a second member provided with a sliding guide surface slidingly contacting the sliding guide surface of the first member and freely movable relatively to the first member, and a resin liner provided on at least a part of the sliding guide surface of the second member and slidingly contacting the sliding guide surface of the first member, wherein the method comprises: a first step of forming the sliding guide surface on the first member, a second step of fixing a thermosetting resin which constitutes the resin liner on the whole or a part of the sliding guide surface of the first member by an injection molding operation with the first member inserted as a core in a metal mold, a third step of molding the second member, which covers the sliding guide surface of the first member, by a metal molding operation with the resin liner-fixed first member placed firmly as a core in a metal mold, and thermally curing at the same time the resin liner with the heat working on the sliding guide surface of the first member during the molding of the second member, and a fourth step of forming a clearance between the sliding guide surfaces of the first member and second member by exerting an external force on the first member or the second member, and thereby enabling a relative movement of the second member with respect to the first member to be made.
