WORK VEHICLE

A dump truck includes front wheels disposed on left and right of a machine body frame to be steered, rear wheels disposed on the left and the right of the machine body frame, a side obstacle sensor that is provided on a side of the machine body frame to detect an obstacle, and a controller configured to output a notification signal to a notification device when an obstacle is detected by the side obstacle sensor. In the dump truck, the side obstacle sensor is provided at a position between the front wheel and the rear wheel on the side of the machine body frame, at which a virtual plane along an outer side face of the front wheel positioned correspondingly to a maximum steering angle steered in the maximum in a direction in which the front wheel becomes an inner wheel crosses an outer side face of the machine body frame. Consequently, a detection range of the obstacle sensor can be suppressed from being narrowed.
