1. A driving device for a hybrid vehicle having an engine and a motor comprising:

  • a first driving force transmission path that transmits driving force of the engine to drive wheels of the vehicle;

    a second driving force transmission path that transmits driving force between the motor and the engine;

    a first torque fluctuation absorbing mechanism that can absorb torque fluctuations on the first driving force transmission path; and

    a second torque fluctuation absorbing mechanism that can absorb torque fluctuations on the second driving force transmission path,wherein driving force of the motor is transmitted via both the first torque fluctuation absorbing mechanism and the second torque fluctuation absorbing mechanism when transmitting the driving force of the motor to the engine in the second driving force transmission path at a time of starting the engine,wherein the driving force of the engine is transmitted via the first torque fluctuation absorbing mechanism, out of the first torque fluctuation absorbing mechanism and the second torque fluctuation absorbing mechanism, when transmitting the driving force of the engine to the drive wheels in the first driving force transmission path while the vehicle is running, andwherein the motor is the first motor that can generate power by driving force of the engine, the driving device further comprising;

    a second motor that can supply driving force to the drive wheels and a third driving force transmission path that transmits driving force of the second motor to the drive wheels; and

    a third torque fluctuation absorbing mechanism that can absorb torque fluctuations on the third driving force transmission path,wherein the driving force of the second motor is transmitted via the third torque fluctuation absorbing mechanism, out of the first to third torque fluctuation absorbing mechanisms, when transmitting the driving force of the second motor to the drive wheels in the third driving force transmission path while the vehicle is running.
