<p>PURPOSE: To raise a transmittable torque and minify its cost and entire size by providing a driven gear as the worm gear of a worm gear device, a differential gear as a worm and meshing respective differential gears with each other directly. CONSTITUTION: Driven gears 4, 5 are provided as the worm gear 8a of a worm gear device 8. Differential gears 6, 7 are provided as a worm 8b. The differential gears 6, 7 of respective differential gear couple have an axis making an angle each other and are meshed with each other directly. Thus, a transmittable torque can be raised by the combination of a worm gear screw with a worm screw.</p> |
