2. Description of the Related Art Conventionally, seats of a vehicle such as a wagon are arranged in three rows in the front-rear direction of the vehicle in order to allow a large number of passengers to ride in the vehicle. A front seat including a pair of driver's seat and front passenger seat is provided, a second-row seat is located behind the front-seat seat, and a rear-seat seat is located further behind the second-row seat. But each is provided.
Thus, in a vehicle in which a plurality of rows of seats are provided in the vehicle front-rear direction, when the number of passengers is small, the second row seat is used.
Various structures for folding the hood have been proposed.

For example, in Japanese Patent Laid-Open No. 6-320991, when the number of passengers is small, the seat in the second row is folded substantially parallel to the floor surface, and the seat in the rear seat is folded in the second row. There is disclosed a vehicle seat structure that moves forward of the vehicle so as to be above the seat and is held in a seatable state at that position.

According to the above seat structure, when the number of passengers is small, the rear seat moves to the front of the vehicle, which is above the folded second row seat, so that it is provided behind the rear seat. It is possible to increase the volume of the cargo space that is stored.

However, according to the above-mentioned prior art, in a vehicle in which passengers are rarely seated and used in all of the front seats, the second-row seats and the rear seats, the number of passengers is usually small. When the second-row seat is folded on the floor surface and the rear seat is moved forward of the vehicle so as to be above the folded second-row seat, the luggage compartment volume can be expanded. However, the distance between the front seat and the rear seat becomes narrower. On the other hand, if the second-row seats are simply folded onto the floor surface and the rear seats are not moved forward of the vehicle, the flat floor surface cannot be used as a living space, and Even in such a case, there is a problem that it is not possible to secure a large living space for an occupant seated on the rear seat.
