PROBLEM TO BE SOLVED: To simplify a structure by constituting so that a casing is connected to and released from a driving unit by at least the specific number for separating clutches arranged in the casing. SOLUTION: At least a single separating clutch 20 is arranged in a casing 9 so that this separating clutch 20 is controlled by medium pressure of a chamber 24. The separating clutch 20 has particularly advantageously an electric machine. Among the machine, a rotor 29 is arranged in a holder 32 for surrounding the casing 9, and a stator is fixed to the nonrotatable stationary part of a driving unit and/or a transmission device. When actuating the electric machine, the casing 9 rotates when the separating clutch 20 does not frictionally engage yet to drive an oil pump. The oil pump supplies high pressure in the chamber 24 to release the separating clutch 20. With this constitution, the separating clutch 20 can be housed without the additional casing part, so that a structure can be simplified. |
