PURPOSE:To enlarge a contact area between a cam face and rolling member, by separating a clutch body into a plate part and housing part and a plurality of pieces of the rolling members is held in an axial direction. CONSTITUTION:A clutch body 1 is constituted with a plate part 4 formed into about a triangular platelike state and a housing part 6 fixed on the plat part 4 with a plurality of pieces of fixing screws 5, the plate part 4 is connected by a spline 7 provided in a central hole by cutting with a rotating shaft 2 and a rotating component 3 is fitted in the housing part 6 rotatably. Cam faces 10 with which two pieces of rollers 9a, 9b are come into contact as a plurality of pieces of rolling members held in an axial direction are formed respectively on three pieces of cams which are provided on the plate part 4 in the circumferential direction of the same at equal intervals and confronting with the external circumferential surface of the rotating component 3 and these rollers 9a, 9b are held between the cam faces and rotating component 3. |
