• and
• a cooling-air introduction port provided in an electrical device which is disposed under the rear floor, the electrical device driving a motor for driving the vehicle, an intake air space formed between a lower surface of the seat cushion of the rear seat, in an unfolded state, and an upper surface of the underseat floor, wherein the intake air space is in communication with a cooling-air introduction port of the electrical device, and
• wherein, when the rear seat is in a folded state, a folded air intake space is formed at least between the lower surface of the seat cushion of the rear seat and the underseat floor and/or between the seat cushion of the rear seat and the seat back, the folded air intake space also being in communication with the cooling-air introduction port.
