<P>PROBLEM TO BE SOLVED: To obtain retainers capable of improving lubricating property of rollers while maintaining high strength and an oscillating inner gearing type gear device incorporating the retainers and having high lubricating property. <P>SOLUTION: The retainers 34, 35, which retain a plurality of the rollers 60, 62, include a pair of first and second ring bodies 34A, 34B, which determine both end positions of each of a plurality of the rollers 60, 62, and connection bodies 34C, which connect the first and second ring bodies 34A, 34B and positions the circumferential directional positions of a plurality of the rollers 60, 62. Recessed portions 34E, 34F, which become passages of a lubricant, are formed at the axial intermediate portions of the connection bodies 34C and a radial dimension L6 of the base end portions 34C1 of the connection bodies 34C adjacent to the first and second ring bodies 34A, 34B is larger than the radial dimension L7 of the portions where the recessed portions 34E, 34F are formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
