PROBLEM TO BE SOLVED: To provide a porous solid lubricant filled universal coupling which limits the oozing lubricating oil quantity to a required minimum with a long life and can be manufactured at low cost. SOLUTION: The porous solid lubricant filled universal coupling 1 includes the porous solid lubricant 10 filled around a ball (rolling body) 6, and the porous solid lubricant is formed by baking the blend containing the resin and the lubricant at least, and the lubricant is formed by impregnating in the sintering body of the resin. Its blending ratio is 10-150 weight part against the resin ratio 100, and the resin is a thermoplastic elastomer and a thermoplastic polyurethane elastomer especially or a thermoplastic polyester elastomer. The resin is the resin pellet of more than 0.01 mm and less than 1mm for one side and its aspect ratio is more than 2 and less tan 50. COPYRIGHT: (C)2008,JPO&INPIT |
