摘要： PROBLEM TO BE SOLVED: To restrain abrasion in an engaging part between an engaging piece, and a clutch outer ring and a clutch inner ring.
SOLUTION: A bearing part 13 and a clutch part 14 are juxtaposed in the axial direction between the clutch outer ring 11 and the clutch inner ring 12, and the bearing part 13 is formed with a grease reservoir 29 between a seal 21 and a ball 16 for sealing an outer end part in the axial direction of the bearing part inside. A retainer 17 for holding a sprag 18 of the clutch part 14 and a bearing cage 15 for holding the ball 16 of the bearing part 13 are integrally formed. The seal 21 is formed by integrating a noncontact projection part 28 into the ball 16, and this projection part 28 is arranged while filling up the grease reservoir 29. Grease supplied to a space on the clutch part 14 side between the clutch outer ring 11 and the clutch inner ring 12, is prevented from being pushed out to the grease reservoir 29 by this projection part 28, and the abrasion is restrained in the engaging part between the sprag 18, and the clutch outer ring 11 and the clutch inner ring 12.

摘要： PROBLEM TO BE SOLVED: To provide a cage which generates no lubricant-oriented gas even in use under vacuum condition, has low dust generation properties, features low torque and can be used for a long period of time by increasing oil content. SOLUTION: The cage for the roller bearing for supporting a rolling element of the roller bearing used for a rotation part of a satellite is composed of a porous resin molded body having a communication hole rate of 30% to 60% and impregnated with alkylation cyclopentane oil. The porous resin molded body has communication holes formed by molding resin containing a pore forming material to form the molded body and then extracting the pore forming material from the molded body by using a solvent which dissolves the pore forming material but does not dissolve the resin. The resin structuring the porous resin molded body is polyether ether ketone resin. COPYRIGHT: (C)2007,JPO&INPIT
