ABSTRACT:
A traction-drive type driving-force transmission mechanism includes a sun roller having a first central axis about which the sun roller is rotatable. Shafts are provided and each has a second central axis aligned parallel to the first central axis. Planetary rollers are arranged rotatably along an outer peripheral surface of the sun roller and are supported respectively by the shafts. A guide member guides each shaft displaceably in a radial direction of the sun roller while maintaining the parallel relationship between the first and second central axes. A pressing member presses each planetary roller against the outer peripheral surface of the sun roller so that a driving force can be transmitted by a traction force between the sun roller and each of the planetary rollers.
