<P>PROBLEM TO BE SOLVED: To improve action stability and durability of a roller clutch that is a one-way clutch, by certainly preventing partial wear of a roller. <P>SOLUTION: The hardness of the roller 14 is set to be higher than the hardness of an outer peripheral surface of a clutch inner wheel 11 (or an inner peripheral surface of a clutch outer wheel 12, namely either one that does not have a cam surface 16), thereby certainly preventing partial wear of the roller 14. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
