1. A power train of a hybrid vehicle, comprising:

  • an internal combustion engine;

    a motor that is driven by electric energy;

    a first clutch that is disposed on a first surface of a retainer integrally mounted on a transmission input shaft of an automatic transmission to selectively transmits power of the engine directly to the transmission input shaft wherein the first clutch is disposed radially inside a rotor of the motor; and

    a second clutch that is disposed on a second surface of the retainer opposite the first surface to selectively transmits power from the motor to the same transmission input shaft as the first clutch wherein the second clutch is disposed radially inside the rotor of the motor, the diameter of the second clutch larger than that of the first clutch,wherein the first clutch and the second clutch are disposed to be sequentially arranged along a radial direction of the transmission input shaft,wherein the inner circumference of a rotor shaft of the motor is supported by an outside of a front shaft through a first bearing and an outer circumference is supported by a transmission case through a second bearing, the first bearing and the second bearing disposed inside the inner circumference of the rotor of the motor while overlapping each other in the radial direction of the front shaft,wherein a motor speed sensor is disposed between the rotor shaft of the motor and the transmission case, and the motor speed sensor is positioned inside the inner circumference of the rotor, andwherein the first clutch and the second clutch, the first bearing and the second bearing supporting the rotor shaft of the rotor and the motor speed sensor are disposed inside the inner circumference of the rotor of the motor.
