PURPOSE:To smoothly roll outer rollers in transmitting grooves with proper attitude maintained and prevent power loss and vibration due to sliding friction, by providing means for restricting inclination of holders between an outer member and the holders. CONSTITUTION:When transmitting shafts 1 and 2 are bent relative to each other in a plane including axes of the shafts 1 and 2 and axes of trunnions 8, inner rollers 9 are inclined in holders 10 to slightly slide on the trunnions 8, and outer rollers 12 are reciprocatingly rolled on one side surface of transmitting grooves 5. At this time, inclination of the holders 10 in the transmitting grooves 5 is restricted because restriction flanges 13 abut against rail portions 6. Therefore, the outer rollers 12 supported to the holders 10 are always restrained from being inclined, thereby smoothly rolling in the transmitting grooves 5. Further, also when both the transmitting shafts 1 and 2 are axially displaced relative to each other, the outer rollers 12 are not inclined, and are allowed to smoothly roll in the transmitting grooves 5. |
