Document Type and Number:
Japanese Patent JP2008196587
Kind Code:

Abstract:

To provide a sliding member having a low friction coefficient and stable sliding property while satisfying quietness and low vibratility over a long period, and to provide a sliding device using the same.

The sliding member 4 comprises a sintered metal porous body 5 for sliding with a shaft 2, and a lubricant supply material 6 arranged at a site adjacent to the sintered metal porous body 5. It is slidingly guided to the outer peripheral face (the sliding face) 3 of the shaft 2. The lubricant supply material 6 is formed by firing a mixture containing at least a resin and lubricant. The lubricant is impregnated with a sintered body of the resin. The lubricant is incorporated in the resin at a rate of 10-150 pts.wt. to 100 pts.wt. The resin is a thermoplastic elastomer, particularly, a thermoplastic polyurethane elastomer or a thermoplastic polyester elastomer. It is a pelletized resin with one side being 0.01-1 mm and its aspect ratio being 2-50. The sliding device uses the sliding member 4.
