A first rotary shaft is rotated by a driver and rotatively connected to a first rotary load. A second rotary shaft is rotatively connected to a second rotary load. A hydraulic pump includes a first rotor disposed on the first rotary shaft so as to be rotated together therewith. A second rotor is disposed on the second rotary shaft so as to be rotated together therewith. The second rotor acts so that, when a revolution speed difference has occurred between the first and second rotary shafts, the first and second rotors are each relatively slided on a sliding surface thereon by relative rotation corresponding to the difference, to heighten the pressure of liquid-tightly interposed oil and then supply the pressure-heightened oil. A multiple-disk clutch includes a group of engaging members disposed on the first rotary shaft so as to be rotated together therewith and so as to be movable in the axial direction thereof relative to the first rotary shaft, and another group of engaging members which are disposed on the second rotary shaft so as to be rotated together therewith. The latter engaging members are placed between the former engaging members so as to constitute a multiple-disk clutch, thus making is possible to engage both the groups of engaging members with each other to transmit torque.
