PURPOSE:To facilitate adjustment of backlash by changing distance between axes of two gears continuously by sliding one of casings of a pair of gears relatively. CONSTITUTION:A motor 26, a shaft 23 and a gear 21 are integrally mounted on a casing 1. While a gear 22 on a driven side is mounted on a casing 2. The gears 21, 22 are arranged by shifting laterally and engaged with each other so that the distance of their vertical directions becomes smaller than the sum of radii of both gears. Under such a condition, one of the casings 1 is slid at a right angle direction to the shaft 23 to adjust the distance between axes of both gears 21, 22. |
