1. A hybrid power unit, comprising:

  • a main power source;

    a rotation output shaft, to which driving force output by the main power source is transmitted;

    a generator, to which the driving force of the main power source is transmitted, the power being distributed to the rotation output shaft and the generator;

    a battery, to which electricity generated by the generator is charged;

    a motor driven by at least one of electricity from the generator and electricity from the battery;

    a transmission transmitting the driving force of the motor to the rotation output shaft;

    a first reduction section that reduces the output of the motor when the transmission is shifted;

    a charge determining section determining whether charging of the battery is permitted; and

    a second reduction section, wherein if the charge determining section determines that charging of the battery is not permitted in a period where the first reduction section reduces the output of the motor, the second reduction section reduces a power generation amount of the generator.
