Abstract
Abstract To smoothly perform a shift change by the actuator with a simple structure, a drive motor M as a running drive source is connected with a drive motor electronic motor unit 103 through a FET driver 107. A change motor 61 for driving a shift drum 62 is connected with a change motor electronic control unit 111 through a FET driver 112. When a drive motor electronic control unit 103 outputs the speed change signal on the basis of the detection signal of an accelerator opening sensor 106 and a drive motor rotational speed sensor 104, the output of the driver motor M is temporarily reduced or stopped to release the meshing surface pressure of the gear trains of the transmission T, and during the period thereof, a shift drum 62 is driven by the change motor 61 for performing the shift change. After completion of the shift change, the output of the drive motor M is smoothly increased.
