PURPOSE:To remove backlash, by providing such an arrangement that two gears are meshed with a gear, and are exerted with torques in opposite directions with respect to each other by means of a resilient member. CONSTITUTION:Two gears 2a, 2b are superposed and meshed with a gear 1, and as well are exerted with torques in opposite direction with respect to each other by means of resilient member 6 to hold the associated gear 1 therebetween or to widen therebetween. With this arrangement power is transmitted in such a condition that a tooth shift takes place corresponding to the backlash between the gears 2a, 2b, thereby the backlash may be removed. |
