    • 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.

    • The contact angle of each of the balls of a thrust ball bearing for use with power rollers is deviated from 90 degrees. Thus the power roller is not easily displaced in the radial direction when radial loads are exerted. Also, the distance in the radial direction between the acting point of loads applied to the circumferential surface of the power roller and the contacting point of the rolling surface of each ball and the inner ring raceway is decreased. In this way, any bending stresses to be exerted on the power roller by the application of the aforesaid loads are eased.In another embodiment, the thickness dimension of the outer ring is made greater in the portion closer to the inner circumference, and smaller in the portion closer to the outer circumference with the outer ring raceway as boundary. Thus the width dimension of the circumferential surface of the power roller is made larger, and the strength of the outer ring is enhanced against bending stresses.
    • 与动力辊一起使用的推力球轴承的每个球的接触角偏离90度。 因此,当施加径向载荷时,动力辊不容易沿径向位移。 此外,施加到动力辊的圆周表面的负载作用点和每个球的滚动表面与内圈滚道的接触点之间的径向方向上的距离减小。 以这种方式,通过施加上述负载来施加在动力辊上的任何弯曲应力都被减轻。 在另一个实施例中,外环的厚度尺寸在靠近内圆周的部分中更大,而在外圈滚道作为边界的情况下,更靠近外周的部分较小。 因此,动力辊的圆周表面的宽度尺寸变大,并且外圈的强度相对于弯曲应力增强。
