Wiring configuration for throttle body in small vehicle

The present invention provides a small vehicle to a wiring configuration for the throttle, which can cope with the swing of the power unit while suppressing the processing space of the wiring, the wiring to improve the connection workability. The small vehicle (1), the engine (2) and the power transmission device (3) integrated and below the seat (6) is arranged pivotably mounted on the frame (4) of the power unit (5) the small vehicle wiring structure to the throttle body, the throttle body (52) is disposed between the power unit and the seat, opening degree sensor (68) detecting the throttle opening degree is provided oriented in the vehicle width direction a throttle shaft axis (64), for the actuator (70) is mounted proximity sensor opening from the same direction to control the throttle of the throttle body, the first wiring coupler opening sensor (80) and actuator second wiring coupler (81) back and forth in the same direction, respectively, and arranged in a direction with respect to the throttle valve axis intersecting.
