A double clutch may include an input shaft, a first output shaft disposed coaxially with the input shaft, a second output shaft enclosing the first output shaft and disposed coaxially with the first output shaft, a first clutch pack disposed between the first output shaft and the input shaft, a second clutch pack disposed between the second output shaft and the input shaft, an electromagnet disposed between the first clutch pack and the second clutch pack, a first permanent magnet and a second permanent magnet disposed such that the same poles of the first and second permanent magnets face the electromagnet at both sides of the electromagnet, a first ball ramp operating to press the first clutch pack, as the first permanent magnet moves toward the electromagnet, and a second ball ramp operating to press the second clutch pack, as the second permanent magnet moves toward the electromagnet.
