できる。Since the positions of the seats S L and S R can be adjusted in the longitudinal direction of the vehicle body, the positions of the first reinforcing members 7 and 7 and the second reinforcing members 16 and 16 also move forward and backward. As is clear from FIG. 3, when the seats S L and S R are at the frontward positions, the flanges 8 at the outer ends of the first reinforcing members 7 and 7 are connected to the third doors of the front doors D FL and D FR . When the seats S L , S R are at the rearward positions facing the reinforcing members 9, 9, the flanges 8, 8 at the outer ends of the first reinforcing members 7, 7 are connected to the third doors D RL , D RR . The reinforcing members 10 face each other. Also, regardless of the position of the sheets S L and S R in the front-rear direction, the flanges 1 at the outer ends of the second reinforcing members 16
8 and 18 are fourth reinforcing members 1 formed long in the front-rear direction.
9 and 19 can be confronted. Further, the sheet S L, even S R is in any position in the longitudinal direction, first, second reinforcing members 9; to 17 and 17 back and forth direction; flange 11, 11 the inner end of the 16, 16 It can face any part of the load transmission member 13 formed long.

できる。Since the positions of the seats S L and S R can be adjusted in the longitudinal direction of the vehicle body, the positions of the first reinforcing members 7 and 7 and the second reinforcing members 16 and 16 also move forward and backward. As is clear from FIG. 3, when the seats S L and S R are at the frontward positions, the flanges 8 at the outer ends of the first reinforcing members 7 and 7 are connected to the third doors of the front doors D FL and D FR . When the seats S L , S R are at the rearward positions facing the reinforcing members 9, 9, the flanges 8, 8 at the outer ends of the first reinforcing members 7, 7 are connected to the third doors D RL , D RR . The reinforcing members 10 face each other. Also, regardless of the position of the sheets S L and S R in the front-rear direction, the flanges 1 at the outer ends of the second reinforcing members 16
8 and 18 are fourth reinforcing members 1 formed long in the front-rear direction.
9 and 19 can be confronted. Further, the sheet S L, even S R is in any position in the longitudinal direction, first, second reinforcing members 9; to 17 and 17 back and forth direction; flange 11, 11 the inner end of the 16, 16 It can face any part of the load transmission member 13 formed long.
