<P>PROBLEM TO BE SOLVED: To uniformly generate traction in the axial direction, by always pressing planetary rollers in parallel to a peripheral surface of a sun roller. <P>SOLUTION: This traction power transmission device has the sun roller 4 rotatably supported in a casing 2 and a plurality of planetary rollers 22 arranged along the peripheral surface of the sun roller 4 and supported rotatably around axes parallel to the central axis of the sun roller 4. The traction power transmission device can transmit motive power by traction between the sun roller 4 and the planetary rollers 22 by pressing the planetary rollers 22 to the peripheral surface of the sun roller 4. A shaft member 24 of the planetary rollers 22 freely moves in the radial direction of the sun roller 4 while holding parallelism to the central axis of the sun roller 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
