<P>PROBLEM TO BE SOLVED: To provide a traction power transmission device usable up to the mechanical service life, while enabling automatic adjustment of pressing force. <P>SOLUTION: This traction power transmission device includes a sun roller 4, a plurality of planetary roller mechanisms 22 rotatably arranged along a peripheral surface of the sun roller, and a pressing member 10 having a pressing surface 10b pressing the planetary roller mechanisms 22 toward the peripheral surface of the sun roller 4 and capable of transmitting motive power by traction between the sun roller 4 and the planetary roller mechanisms 22. Each of the planetary roller mechanisms 22 includes a first planetary roller 22a rotating along the peripheral surface of the sun roller 4, and a second planetary roller 22b allowing its peripheral surface to abut on a peripheral surface of the first planetary roller 22a, abutting on the pressing surface 10b and pressing the peripheral surface of the first planetary roller 22a to the peripheral surface of the sun roller 4 when rotating the planetary roller mechanisms 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
