PROBLEM TO BE SOLVED: To prevent a rotor guide for holding a rotor of an electromagnetic clutch from being tilted with respect to an outer ring, in a rotation transmission device for controlling a two-way clutch by the electromagnetic clutch. SOLUTION: The two-way clutch 10 is integrated between the outer ring 1 and an inner ring 2, and the electromagnetic clutch 20 is provided side by side together with the two-way clutch 10. The rotor guide 27 for holding the rotor 22 of the electromagnetic clutch 20 is fitted on the circumference of the opening end of the outer ring 1. An engaging groove 29 is formed on the end inner circumference of the rotor guide 27, and a notched part 30 extending in the axial direction from the end face is provided, and a detent piece 31 formed on the opening end face of the outer ring 1 is fitted into the notched part 30, to thereby stop rotation of the rotor guide 27. A slipping-out preventive groove 32 successive to the engaging groove 29 is formed on the inner diameter surface of the detent piece 31, and a retaining ring 33 is mounted across the slipping-out preventive groove 32 and the engaging groove 29. A projection part 35 stored in a separation part 34 of the retaining ring 33 is formed on the engaging groove 29, to thereby stop rotation of the retaining ring 33. COPYRIGHT: (C)2008,JPO&INPIT
