Abstract: A front straightening portion is formed at a front portion of a main body portion of a spat. In the front straightening portion, a front inclined surface is inclined backward with respect to a vehicle with decrease in distance to a lower side of the vehicle in a lateral view, and front lateral surfaces extend forward with respect to the vehicle from both end portions of the front inclined surface in a vehicle width direction, respectively. A traveling wind that hits the front lateral surfaces flows toward the front inclined surface side, and is caused to flow out downward with respect to the vehicle from the front straightening portion together with a traveling wind. The flow velocities of the traveling winds increase, the air resistance of the vehicle can be reduced, operation stability of the vehicle can be enhanced, and riding comfort performance of the vehicle can be enhanced.
