Next, the rear seat structure of the motorcycle 1 will be described.
With reference to FIGS. 1 to 8, the seat 20 includes a front seat 21 in which the driver A is seated and a rear seat 22 in which the passenger B is seated. For example, the front seat 21 and the rear seat 22 are separated from each other and are arranged adjacent to each other in the front-rear direction of the vehicle. The seat surface portion 21A forming the upper surface of the front seat 21 and the seat surface portion 22A forming the upper surface of the rear seat 22 each have an elastic cushion layer.

The rear seat 22 is provided with a side backrest 23. The overall shape of the side backrest 23 is U-shaped. The side backrest 23 expands to the left and right sides from the first state M1 (see FIGS. 1, 3, 5, and 6) forming a flat seating surface on the rear seat 22 and the first state M1. It is variable between the second state M2 (see FIGS. 2, 4, 7, and 8), which is arranged so as to stand up above the seating surface.
