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.
A motor driving vehicle provided with a decelerator, comprising
An electric vehicle having a motor driving device provided with a decelerator, which comprises an electric motor, an output shaft coaxially arranged with a motor rotational shaft of said electric motor through a planetary gear decelerator, and a casing enclosing at least said electric motor and said planetary gear decelerator, said motor driving device being mounted on each wheel of said vehicle by said wheel being mounted on said output rotational shaft.
