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 1):
An oil-retaining sintered bearing comprising:\n a bearing hole; a sliding surface supporting an outer peripheral surface of a shaft; and an oiling surface, wherein the sliding surface and the oiling surface 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 is not larger than 10%; and a surface open rate at the oiling surface is larger than 10%.
