<P>PROBLEM TO BE SOLVED: To surely transmit the rotation of a rotating shaft to each of a plurality of planetary rollers without causing losses. <P>SOLUTION: The plurality of planetary rollers 21 are embedded between an inside diameter face of an outer ring member 5 and an outside diameter face of the rotating shaft 10. Roller shafts 19 with the same number of the planetary rollers 21 are movably arranged at a rotatable carrier 14 in the radial direction with the rotating shaft 10 as a center, and the planetary rollers 21 are rotatably supported by the roller shafts 19. A tensile coil spring 22 is bridged between a pair of the roller shafts 19 which adjoin each other in the circumferential direction, a pair of the roller shafts 19 are energized toward the inside of the radial direction, the planetary rollers 21 are made to pressure-contact with the outside diameter face of the rotating shaft 10, and a slide is prevented from being generated at a contact part between the planetary rollers 21 and the rotating shaft 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
