And the distance (dimension) is not changed.
That is, a rotor (rotor) 10 that constitutes a motor is attached to a clutch cover 6 that houses a clutch disk 4 of a vehicle already mounted with only the internal combustion engine 2 (a vehicle designed for mounting only the internal combustion engine). Provide.
On the other hand, the clutch housing 7 is provided with a stator (stator) 11 constituting a motor. The rotor (rotor) 10 and the stator (stator) 11 constitute a motor, which is hybridized.

As is clear from the comparison between FIG. 4 and FIG. 1, in the conventional motor arrangement structure, the internal combustion engine 21 and the flywheel 23 In between, the motor 22 is arranged.
Therefore, the motor 22 cannot be arranged unless the basic configuration such as the arrangement and dimensions of the internal combustion engine 21, the flywheel 23, the clutch disk 24, the transmission 25, and the like are changed.

On the other hand, in the arrangement structure of the motor according to the present invention, the rotor (rotor) 10 is provided in the clutch cover 6 already arranged in the vehicle (the clutch cover 6 itself is used as the rotor (rotor)), and the one-way clutch Since the stator (stator) 11 is provided in the housing 7, the motor can be arranged without changing the basic configuration such as the arrangement and dimensions of the internal combustion engine 1, the flywheel 2, the clutch disk 3, and the transmission 4. .
Furthermore, by exchanging the clutch cover 6 and the clutch housing 7, any vehicle including a manual transmission can be hybridized.

A plurality of permanent magnets 10 a are arranged in the circumferential direction on the outer peripheral surface 6 a of the clutch cover 6 to form a rotor (rotor) 10.
The rotor 10 is not limited to the permanent magnet 10a, and may be an electromagnet. A cage-type or reluctance-type rotor may also be used. Thus, in the case of a permanent magnet type, cage type, or reluctance type rotor, it is not necessary to provide electrical wiring to the rotor, and electrical wiring is sufficient because the wiring of the stator winding is sufficient.

An inner wall 7 a of the clutch housing 7 that faces the outer peripheral surface 6 a of the clutch cover 6 is formed in parallel with the input shaft 8 of the mission 5.
