る。However, in such a conventional automobile seat, since the reinforcing members are provided at positions where the seat cushions of the left and right seats and the inside of the seat back have different heights, the predetermined size is provided. It is not possible to evenly receive the load from a car or a moving barrier (a jig for applying a load during a side impact test) that enters at the height of the vehicle. Further, since the range for receiving the load is large in the front-rear direction, the front-rear range in which the reinforcing member is provided becomes large, which may significantly impair the storage function of the door.
