<P>PROBLEM TO BE SOLVED: To prevent grease leakage of a reverse input preventing clutch with the grease sealed inside. <P>SOLUTION: A shielding ring 14 as a diameter direction sealing member which is close to an inner circumferential surface of a cylindrical end part 7a of a pressing cover 7 is fitted into a retainer cylinder part 9b fitted into an outer circumference of an input shaft 1. An oil seal 16 as an axial direction sealing member, which is in slide-contact with an end surface of an oil-impregnated sintered bearing 15 fixed on a housing, is fitted into an output shaft 2. Thereby, even when rotation is transmitted from an input side member to an output side member, and the grease sealed inside a fixing member 8 is stirred, the grease does not leak. <P>COPYRIGHT: (C)2009,JPO&INPIT |
