PURPOSE:To make the titled structure light in weight and also compact by placing a shaft supporting part of a crank shaft, a decelerating mechanism, and an output shaft of an electrically driven motor, on the same axis to each other. CONSTITUTION:A stator coil 4 is fixed to the inside peripheral part of a motor case 3, and a fly-wheel to which a rotor core 6 has been fixed is provided concentrically to an output shaft 14, and also so as to be rotatable. Between the fly-wheel 5 and the output shaft 14, a driving clutch is installed, and an electrically driven motor 1 provided with a brake against the output shaft 14, and a crank shaft 42 which has been connected to the output shaft 14 of the electrically driven motor 1 through a planet gear decelerating mechanism 2 are provided. Also, a shaft core of the shaft supporting part of the crank shaft 42, the center of the planet gear decelerating mechanism 2, and a shaft core of the output shaft 14 of the electrically driven motor 1 are placed on the same straight line. Accordingly, by attaching the same electrically driven motor to both sides of the crank shaft, respectively, the structure is simplified and a torque of two times can be obtained. |
