A power transmission apparatus disposed includes: a motor for driving wheels, and transforms kinetic energy at the driving path to electrical energy; a normal close type clutch that includes an input and an output and is selectively set in an engaging state and a released state, wherein the clutch is normally set in the engaging state by a biasing member and is set in the released state when hydraulic pressure is applied; a hydraulic-pressure feeding device for supplying the adjusted hydraulic pressure to the clutch; and a control device for controlling the feeding device. When changing the clutch from the engaged state to the released state, if the difference between rotation numbers of the input and the output becomes equal to or larger than the predetermined value, the control device controls the feeding device to bring the clutch to a state just before the engaged state.
