Abstract: A double clutch apparatus for a hybrid electric vehicle having a motor and an engine includes: first and second clutches transmitting a motor torque and an engine torque to first and second input shafts; and first and second slave cylinders disposed at a transmission case and configured to respectively operate the first and second clutches in an axial direction. In particular, a rotor hub of the motor is rotatably supported by an end of a radially interior side of a front cover, and is connected to the first input shaft through a clutch retainer of the second clutch and a first connection member to transmit the motor torque to the first input shaft. In addition, the first and second clutches are disposed in parallel in an interior circumference of the rotor hub to selectively transmit the engine torque to the first and second input shafts, respectively.
