PURPOSE:To provide a slide bearing, a slide bearing device or a small-sized motor capable of improving mechanical strength stability of abrasion coefficient and abrasion resistance to same degree or above as those of a conventional sintered oil-containing bearing and having fewer parts so as to provide smaller size and lightening. CONSTITUTION:This slide bearing device is obtained by integrally molding a housing 7 having a circular hole 6a supporting a rotating shaft 3 and a through hole 8 from a resin composition composed of 20-40wt.% of a synthetic resin such as a polyphenylene sulfide resin, 20-60wt.% of an inorganic filler such as mica, 10-30wt.% of a fiber reinforced material such as carbon fiber, 3-7wt.% of a lubricating oil such as fatty acid ester oil and 1-5wt.% of oil- retaining material such as tale. This slide bearing is composed of the composition. This small-sized motor is obtained by attaching the slide bearing to the housing 7 retaining a stator 2 and supporting the rotating shaft 3 of a rotor 1 with the slide bearing. |
