PURPOSE:To enable power transfer with a simple construction while keeping the relation of proportion surely, by coupling the rotating shafts of two motors and the output member with a differential device and displacing the output member according to the displacement of an input member. CONSTITUTION:A lever 1 of a potentiometer at a neutral state is moved to another position snown in dotted lines and a motor M1 is rotated at the speed according to a resistance value of resistance boards 2, 2'. Thus, a differential casing 25 is rotated, and an output shaft 32 is rotated via gears 28, 29, 31 and wipers 13, 13' are shaken by the rotation. The wipers 13, 13' are shaken to the position where a motor M2 is given of the same number of reverse revolutions as that of the motor M1 and the rotation of a casing 25 is stopped at this position. Thus, the displacement between input and output members can be given of sure relation of proportion for the transfer of power. |
