PROBLEM TO BE SOLVED: To provide a power changeover device allowing the transmission of power without an increase in cost. SOLUTION: The power changeover device 19 having a fork shaft 8 for performing linear motion with the rotating force of a motor 3 converted into linear motion, a shaft 11 for performing rotation with the drive of an engine, a slider 9 provided between the shaft 11 and the fork shaft 8 for movement with the motion of the fork shaft 8, and a shaft 12 to be connected to a slider 9 when moved a predetermined distance for integral rotation with the rotation of the shaft 11 comprises a position sensor 5 for detecting the position of the fork shaft 8 and a control device 4 for previously storing a position where the slider 9 begins to be connected to the shaft 12 with the movement of the fork shaft 8 and driving the motor in a region near the connection position with PWM control.
