ABSTRACT:
A power transmission device includes a pair of gear assemblies and an idle. Each of the gear assemblies includes a first gear having continuous external teeth on a peripheral wall and a second gear having continuous external teeth on a peripheral wall. The first gear and second gear are arranged to form a one-way clutch. When the first gear rotates in one direction relative to the second gear, the first gear is not connected to the second gear. When the first gear rotates in the other direction relative to the second gear, the first gear is connected to the second gear. The external teeth of the first gears in the gear assemblies engage each other, and the external teeth of the second gears in the gear assemblies engage the idle gear. One direction output at the second gear is obtained regardless of an input direction at the first gear.
