PROBLEM TO BE SOLVED: To facilitate assembling by reducing the number of parts and reduce the size in the radial direction, in a rotation transmission device in which a two-way clutch is controlled by an electromagnetic clutch. SOLUTION: The two-way clutch 10 is assembled between an outer ring 1 and an inner ring 2. An electromagnetic clutch 20 is installed together with the two-way clutch 10. A rotor guide 27 is installed between the outer ring 1 and the rotor 22 of the electromagnetic clutch 20. An engagement groove 30 is formed at the outer periphery of the rotor guide 27. A pair of first cutout 31 and second cutout 32 axially extending from both end faces of the rotor guide and crossing the engagement groove 30 are formed at the rotor guide. A rotation stop piece 33 mounted to the outer ring 1 and a rotation stop piece 36 mounted to the rotor 22 are fitted into the first cutout 31 and the second cutout 32 to stop the rotation of the rotor guide 27 and the rotor 22. Engagement projecting parts 34, 37 formed at ends of the rotation stop pieces 33, 36 are engaged with a snap ring 35 fitted into the engagement groove 30 to prevent the rotor guide 27 and the rotor 22 from being extracted.
