A saddle type vehicle includes a seat rail and a seat that is attached to the seat rail. The seat rail includes an outer edge that is placed on an outward side in a vehicle body width direction and an inner edge that is placed on an inward side in the vehicle body width direction and higher than the outer edge. On the other hand, the seat includes a sitting part. When the sitting part sits on an upper surface of the inner edge, a side part of the seat surrounds (covers) the sitting part.
