To provide a layout structure for a motor-driven power steering unit controller configured to take into account the water level at which submergence of the vehicle is expected to occur. In a vehicle including a steering shaft rotatably supported on a vehicle body frame, a steering bar handle attached to the upper end of the steering shaft, a motor-driven power steering unit mounted onto the lower end of the steering shaft, and at least two front wheels, a controller for controlling the motor-driven power steering unit is laid out on the front side relative to the steering shaft and above a horizontal line indicative of the submergence limit of the vehicle.
