In other words, in the first and second seats of the present invention, the backrest is tilted back approximately 180 degrees with respect to the seat, and the upright first and second seats are placed near the back of the front seat. Since the seats can be placed side by side, a large space for the luggage compartment can be provided in the area where both regular seats are left, which is convenient for loading luggage. In addition, in this invention,
The front legs of the first and second seats can be reduced and folded into an upright position, so even if one of the first or second seats is used for seating and the other is folded, the space occupied by the folded seats is reduced. It is small and its front legs are reduced when folded,
Convenient for loading luggage.

Moreover, since the front legs are reduced and folded, the distance between the seats, that is, the distance between the first rear seat of the front seat and the distance between the first rear seat and the second rear seat, is narrow. Since the front legs can be placed significantly further forward than when the front legs are fixed length, the cargo space is It has an amplifying effect.
