Abstract:
A lubricant member of a preferred embodiment of the invention is formed, into a stick-shaped body longer in a lengthwise direction than in a diametrical direction, of a mixture including at least a polyamide resin as a thermoplastic resin, an ultrahigh molecular weight polyethylene, and lubricant oil. A film made mainly of the polyamide resin is formed in the outer peripheral surface of the lubricant member. At the inner side of the film, fibrous crystals of the polyamide resin and the ultrahigh molecular weight polyethylene extend in the lengthwise direction of the lubricant member, and multiple pores are formed. With this structure, the lubricant member is produced with excellent workability without sacrificing the mechanical strength and the lubricating property.
