PROBLEM TO BE SOLVED: To provide a one-way clutch unit capable of reducing the number of part items, shortening axial size, reducing cost, and realizing compactness. SOLUTION: In this one-way clutch unit, a first outer ring part 6 for a one- way clutch 1 is integrated with a second outer ring part 7 for a deep groove bearing 2 to be an integrated outer ring 3, and a first inner ring part 8 for the one-way clutch is integrated with a second inner ring part 10 for the deep groove bearing to be an integrated inner ring 5. The number of part items can be reduced, and the axial size can be shortened, so that cost reduction and compactness can be achieved. Between a taper surface 18 existing between a decagonal outer circumferential cam surface 8A of the first inner ring part 8 and an outer circumferential surface of the second inner ring part 10, and an inner circumferential surface of the integrated outer ring 3, a circular part 17A of a crown-shaped holder 17 is disposed. The increase of the axial size caused by the crown-shaped holder 17 can thus be restricted, thereby the axial size can be shortened. |
