PURPOSE:To reduce a double clutch device in size and thickness by disposing the first clutch disc and the second clutch disc on both sides of a common friction plate in a hydraulic double clutch device. CONSTITUTION:In a double clutch device 12, the first rotor 38 and the second rotor 30 are disposed on both sides of a friction plate 40 as a common friction plate, so that the first and second rotors 38, 30 are driven in the direction of the facing to each other by the first piston 46 and the second piston 50. Accordingly, a partition wall for dividing the interior of a clutch case 26 and a seal member are not required, and only one oil path may be disposed in an output shaft 18, so that the double clutch device 12 can be reduced in size and thickness as a whole to attain high loading ability for a vehicle.
