ABSTRACT:
A motor driving device provided with a decelerator according to the present invention is so structured that a motor rotational shaft 6a and an output rotational shaft 9 are coaxially disposed within a casing 1 thereof, and planetary gears 18, 19, 20, 21, and 22 connect the two rotational shafts 6a and 9.
According to the present invention, a special wall disposed between the motor rotational shaft 6a and the output rotational shaft 9 and for supporting the two rotational shafts 6a and 9 becomes needless to be provided for the casing 1. As a result, the overall length of the casing 1 can be reduced and the shape of the casing 1 can be simplified. Furthermore, the power of the electric motor 6 can be effectively transmitted to the output rotational shaft 9 by the planetary gear decelerating device so that the driving device can output large torque.
