It is composed of a coupling fixing portion 30 for coupling with the connecting portion 20 for fixing on the board (3).

The battery 11, located in the case 10, supplies power to drive the motor 12 and to operate the PCB 15, wherein the PCB 15 is connected to the battery 11. It may include an over-discharge prevention circuit for preventing the discharge below a certain voltage.

The motor 12 receives power from the battery 11 to generate a driving force, and the driving force transmitter 13 is positioned to face the bottom surface of the rear wheel 2 and is generated in the motor 12. The driving force is transmitted to the bottom surface of the rear wheel (2) in close contact. In addition, a bevel gear 19 is provided between the motor 12 and the driving force transmitter 13 to increase the torque while decelerating the motor 12 at an appropriate speed so as to increase the driving force transmitted to the rear wheel 2.
