ABSTRACT:
A bearing comprising a resin layer, a backing strip and an intermediate layer which bonds the resin layer and the backing strip to each other is disclosed. The bearing undergoes a force from the resin layer side. A corrosion preventing layer is formed on each side face of the bearing so as to cover the intermediate layer. The corrosion preventing layer prevents the intermediate layer from being corroded by gas contained in an atmosphere and lubricating oil which are present around the bearing.
