[Operation and effect of the device]

 In the vehicle seat adopting the assembly structure having such a structure, the seat back is fixed to the seat cushion by the first locking means, and the seat cushion is fixed to the vehicle body floor by the second locking means. The lid is fixed to the seat cushion by the third locking means. In this fixed state, the vehicle seat is in a state in which an occupant can sit, and the upper opening of the accommodating portion is covered with a lid.

In this state, in order to store the vehicle seat in the storage portion, the fixing of the seat back to the seat cushion by the first locking means is released, and the seat back is folded to the seat cushion side. When the seat cushion is folded, the fixing of the seat cushion by the second locking means for the vehicle body floor is released, and the seat cushion is rotated backward together with the seat back. As a result, the fixation of the lid body to the seat cushion by the third locking means is released, and the seat back and the seat cushion integral therewith are rotated by about 180 degrees and placed on the lid body. It Therefore, the elevating means descends due to the weight of the seat cushion and the seat back, and the vehicle seat is housed in the housing portion with the seat back folded to the seat cushion side.

As described above, in the assembly structure, the upper opening of the accommodation portion is covered by the lid when the vehicle seat is used, and the lid releases the opening when the seat is accommodated. It is configured to accommodate the seat. For this reason, the upper opening of the accommodating portion is always reliably closed by the lid when the seat is used, and there is no risk that the seated person's foot will face the accommodating portion. In addition, there is no possibility that various foreign substances will enter the accommodation section, and the elevating means can always be operated smoothly during storage.
