Abstract:
An oil-retaining sintered bearing in which friction coefficient can be reduced and a sliding property as a bearing can be improved by supplying a sufficient amount of oil to a sliding surface and preventing the supplied oil from moving to an interior from the sliding surface; a sliding surface  3  supporting an outer peripheral surface of a shaft and a helical oiling surface  4  around a shaft axis of a bearing hole are adjacently formed on an inner peripheral surface of the bearing hole into which the shaft is inserted; a surface open rate at the sliding surface  3  is not larger than 10%; and a surface open rate at the oiling surface exceeds 10%.

Claim (Index 4):
The oil-retaining sintered bearing according to  claim 2 , wherein\n when a length of the bearing hole is \u201cb\u201d; a helical angle of the oiling surface to the shaft axis is \u201c\u03b8\u201d; a width of the oiling surface is \u201cW\u201d; and an area rate of the sliding surface is \u201ca\u201d, sin \u03b8\u2265(W/((1\u2212a)\u00d7b)) and \u201ca\u201d is not smaller than 0.4 and smaller than 1.0.
