A hybrid vehicle driving system comprising:

• a generator which can generate electric power using power of an engine;
• a motor which is driven by electric power to drive wheels;
• a case which accommodates the generator and the motor;
• and
• a power control unit for controlling the generator and the motor,
• the generator and the motor being disposed side by side on a same axis within the case,
• wherein the power control unit is mounted on the case by connecting a unit-side generator connector and a unit-side motor connector which are provided on a bottom surface of the power control unit with a case-side generator connector and a case-side motor connector which are disposed on the case, directly and respectively,
• wherein the case is fixed to a vehicle framework member via a mount member, and
• wherein a fixing point where the case and the mount member are fixed together, and a body-side fixing point where the mount member and the vehicle framework member are fixed together are disposed between the case-side generator connector and the case-side motor connector in a direction in which the case-side generator connector and the case-side motor connector are aligned, when looking at the fixing point and the body-side fixing point from an up-down direction.
