1. A straddled vehicle comprising:
a frame structure including a frame body;
a rear arm swingably supported by the frame structure;
a driving wheel rotatably supported by the rear arm;
a power source unit supported by the frame structure, for supplying electric power; and
a drive unit including
a rotational power transmission mechanism,
a gear box supported by the frame body, and
a drive motor and a control unit that are supported by the gear box,
the drive motor being configured to receive the electric power supplied from the power source unit and to drive the driving wheel, the control unit being configured to control the electric power to be supplied from the power source unit to the drive motor, the gear box accommodating the rotational power transmission mechanism, and the rotational power transmission mechanism being configured to shift a speed of power outputted from the drive motor with a predetermined gear ratio, and to transmit resulting power to the driving wheel, wherein
the drive motor is arranged with an offset toward a first direction from a center of the straddled vehicle with respect to a left-right direction of the straddled vehicle, and is arranged not to overlap the power source unit when viewed in the left-right direction,
the control unit is positioned further in a second direction than the drive motor, and is arranged to overlap the drive motor, but not to overlap the power source unit, when viewed in the left-right direction, the second direction being in the left-right direction and being opposite to the first direction,
the gear box is positioned further in the second direction than the drive motor, and is arranged to overlap the drive motor when viewed in the left-right direction, and
the gear box is also positioned further in the first direction than the control unit, and is arranged to overlap with the control unit, but not to overlap the power source unit, when viewed in the left-right direction, wherein:
the power source unit includes
an electric power generation engine having a rotatable crankshaft, the electric power generation engine being configured to generate power by gas combustion, and to output the rotational power in a form of a torque and a rotation speed of the crankshaft,
an electric power generator that is provided in conjunction with the crankshaft, the electric power generator being driven by the electric power generation engine, to generate the electric power, and
a battery;
the electric power generator supplies the electric power to the battery and/or the drive motor;
the battery is fixed to the frame structure; and
the control unit further controls the supplying of the electric power from the electric power generator to the battery and/or the drive motor.
