<p>A rotation transmission device is provided which generates less colliding sounds and vibrations. The rotation transmission device is configured such that when an electromagnet (53) of an electromagnetic clutch (50) is energized, an armature (51) is attracted toward a rotor (52), so that a control retainer (16A) forming a two-way clutch (10) is moved in the axial direction, whereby the control retainer (16A) and a rotary retainer (16B) are rotated relative to each other in the direction in which the circumferential widths of pockets (27) decrease, thereby disengaging pairs of rollers (15) from the inner periphery of an outer ring (11) and the outer periphery of an inner ring (13). The rotation transmission device includes a shock absorbing member (61) provided on the surface of the armature (51) facing the rotor (52) and configured to absorb impact force when the armature (51) is attracted to the rotor (52) by being elastically deformed.</p> |
