ABSTRACT:
A rotation transmission device has a two-way clutch prevented from engaging while the inner member is rotating unengaged with the outer member. The clutch includes an outer member, a cam ring mounted in the outer member, rollers each mounted between a cylindrical surface of the outer member and a cam surface of the cam ring, and a roller retainer. The device further comprises a rotor mounted between the solenoid and retainer so as to be nonrotatable relative to the outer ring, an armature nonrotatable relative to the retainer and axially movable, a spring axially biasing the armature away from the rotor, and an engaging plate nonrotatable relative to the inner member and axially immovable. The armature and engaging plate engage together when the armature rotates in one direction by a predetermined angle relative to the engaging plate. A high-strength clutch outer ring is mounted in the outer ring.
