摘要： A rotation transmission device is provided which has a minimum play in the rotational direction, which is reliable by preventing the rollers from erroneously engaging during idling, and which has high torque capacity. A control retainer 19A and a rotary retainer 19B are mounted between an outer race 11 having a cylindrical surface 17 on its inner periphery and an inner race 12 having cam surfaces 18 on its outer periphery. An opposed pair of rollers 25 are mounted in each of pockets 24 defined between pillars 21 and 23 of the respective retainers 19A and 19B. A presser member 26 is also mounted in each pocket 24 which biases the pair of rollers 25 away from each other while pressing the rollers against the cam surface 18. A plurality of torque cams 40 are provided between flanges 20 and 22 of the control retainer 19A and the rotary retainer 19B. When the control retainer 19A is moved toward a rotor 52 by the actuation of an electromagnetic clutch 50, the torque cams 40 rotate the control retainer 19A and the rotary retainer 19B in the direction in which the circumferential width of the pockets 24 decreases, thereby disengaging the opposed pairs of rollers 25. When the control retainer 19A is moved away from the rotor 52, the control retainer 19A and the rotary retainer 19B are rotated relative to each other in the direction in which the circumferential width of the pockets 24 increases under the biasing force of the presser members 26, thereby engaging the rollers 25. While the inner race 12 is idling, the presser members 26 prevent the rollers 25 from moving radially outwardly, thereby preventing erroneous engagement of the rollers 25.

摘要： A rotation transmission device is configured such that when an electromagnet of an electromagnetic clutch is energized, a control retainer of a two-way clutch is moved in the axial direction, so that the control retainer and a rotary retainer rotate relative to each other in the direction in which the circumferential widths of pockets decrease, thereby disengaging pairs of rollers from an outer ring and an inner ring. A spring holder is provided which is fixed to an input shaft and kept in abutment with an axial end surface of the inner ring to prevent relative rotation between the control retainer and the rotary retainer in the direction in which the circumferential widths of the pockets decrease, from the neutral position of the rollers. The spring holder is prevented from axial movement to prevent untimely engagement of the two-way clutch. The inner ring is integral with the input shaft.

摘要： A rotation transmission device includes a control retainer and a rotary retainer having bars arranged circumferentially alternating with each other such that pockets are defined between the adjacent pairs of bars. A pair of rollers are mounted in each pocket with an elastic member disposed between the pair of rollers such that the pair of rollers are pushed by the respective bars to their respective disengaged positions when the control retainer and the rotary retainer rotate relative to each other. A spring holder is fitted on an input shaft while abutting one axial end surface of an inner ring. The spring holder has spring support pieces on the outer periphery thereof to prevent radially outward movement of the elastic members. The spring support pieces are plate-shaped members disposed radially outwardly of the elastic members to extend in the axial direction in parallel to the outer periphery of the inner ring.
