Abstract
A traction-drive type driving-force transmission mechanism has a sun roller. Planetary roller units are orbitally movable along an outer surface of the sun roller. A pressing member presses the planetary roller units toward the outer surface of the sun roller and allows a driving force to be transmitted by a traction force between the sun roller and the planetary roller units. Each planetary roller unit includes a first planetary roller rotatably supported by a first shaft and adapted to move orbitally along the outer surface of the sun roller, and a second planetary roller rotatably supported by a second shaft while allowing an outer surface thereof to contact an outer surface of the first planetary roller and the pressing surface, and adapted to press the outer peripheral surface of the first planetary roller against the outer peripheral surface of the sun roller during orbital movement of the planetary roller unit.
