PURPOSE:To obtain a large reduction gear ratio of a reduction gear motor by opposing the bent grooves of the first and second discs through a roll, thereby reducing the size of a reduction gear. CONSTITUTION:Sinusoidal grooves 5, 6 are formed on the flat surfaces 3, 4 of the first and second discs 1, 2, and the discs 1, 2 are opposed through a roll 7. The roll 7 is held by a retainer 8. The retainer 8 is supported via bearings 9, 10 to the discs 1, 2, the disc 2 is secured to a housing 11, and the disc 2 is secured to the housing 11. A flat motor rotor 13 is secured to the flat surface 12 of the disc 1. Since the rotor 13 is rotated by a flat motor stator 14 and secured to the disc 1, the disc 1 also rotates and is reduced at the gear ratio through the retainer 8 at the output. |
