PROBLEM TO BE SOLVED: To reduce the diameter of a one-way clutch and production costs and provide a structure for reliably keeping grease in a cam room. SOLUTION: The outer 23 of a one-way clutch 5 comprises an outer cylindrical member 23A and an inner cylindrical member 23B which are divided into two in the radial direction and both cylindrical member 23A, 23B are fixed to each other by fitting. A plurality of semicircular grooves 29a, 29b which is made by dividing a press fitting-in hole fitted with a pin 24 into two are formed on the fitting-in surface of the outer cylindrical member 23A and an inner cylindrical member 23B. A wedge-like cam room for housing a roller 27 in formed on the inner peripheral side of the inner cylindrical member 23B. The outer cylindrical member 23A has one wall 23a for closing the one side of a cam room in the axial direction and the inner cylindrical member 23B has the other wall 23b for closing the other side of the cam room and the roller 27 is restrained from moving in the axial direction by the wall 23a and the other wall 23b. |
