PROBLEM TO BE SOLVED: To provide a one-way clutch which is decreased in the number of parts and decreased in width in an axial direction. SOLUTION: A one-way clutch comprises an outer ring 2 having a cam surface formed on an inner peripheral surface; an inner ring 1; a plurality of rollers 3a and 3b situated between inner and outer rings; a holder 4 to hold rollers 3a and 3b in a pocket 5; and a spring to energize the rollers 3a and 3b in the direction of a cam surface. The pockets 5 of the holder 4 are formed in two trains 5a and 5b in an axial direction and the rollers 3a and 3b are held in the respective pockets 5a and 5b, and an inner ring 1 consists of first and second inner rings 1a and 1b corresponding to the respective trains of the rollers 3a and 3b. One inner ring 1a forms a fixed member, the other inner ring 1b forms a slide member sliding on one inner ring, and the outer ring 2 is formed in an integral shape corresponding to the roller trains 3a and 3b. |
