Description of the Related Art In recent years, electric vehicles have been actively developed for the purpose of reducing fuel consumption and improving air pollution due to combustion exhaust, noise problems, etc. However, electric motors alone provide sufficient output when accelerating. Since it is difficult to secure it, the development of a vehicle equipped with an automobile composite prime mover that uses an internal combustion engine as an auxiliary is also underway.

である。Conventionally, in this type of motor-vehicle composite prime mover,
Since the electric motor and the internal combustion engine serve as power generation sources and thereby rotate the drive shaft, it is necessary to adjust the mutual rotation speed of the electric motor and the internal combustion engine and the rotation speed of the drive shaft. In addition, the ground height of the drive shaft is a fixed height depending on the size of the tires used in relation to the height of the center of rotation of the wheels, but the electric motors and internal combustion engines that compose the composite prime mover depend on the application. It requires a suitable predetermined height. That is, in particular, the electric motor has a high risk of causing a problem in the electric insulation property against water intrusion, and because of its geometrical characteristic that it is cylindrical with respect to its rotation axis, the mounting position of the electric motor is slightly higher than that of the internal combustion engine. It is necessary to place it in a higher position.
