  For this reason, due to the impact forces F1 and F2, the lower end edge of the side door 40 causes the scuff plate 80 to be moved by the middle of the side door 40 and the impact beam 41 as the casing 10 is displaced toward the side. When the chamber 10 is pushed to the side, the scuff plate 80 including the reinforcing member 85 is immediately pressed against the side portion of the seat device 23 while preventing itself from being deformed, and the side door 40 and the impact beam Further, it is possible to prevent the passenger compartment 10 from being displaced toward the side of each of the midway portions 41 and 41.

  Therefore, since the middle portion of the side door 40 and the impact beam 41 is prevented from being greatly displaced toward the side, the outer edge portion of the side door 40 is simply used as the opening edge of the door opening 39. The occupant in the passenger compartment 10 can be protected more effectively than when the outer surface of the vehicle is pressed against the outer surface of the vehicle or when the impact beam 41 is provided on the side door 40.

  Further, the above-mentioned effective protection of the occupant is achieved by devising a related configuration of the seat device 23 and the scuff plate 80, and each panel plate constituting the opening edge portion of the door opening 39. This can be achieved without increasing the thickness or providing a separate reinforcing material for reinforcing the opening edge of the door opening 39. Therefore, even when the occupant can be effectively protected as described above, it is possible to prevent the mass of the vehicle body 2 from increasing and the configuration of the vehicle body 2 from becoming complicated. It can be maintained well, and the production cost of the vehicle body 2 is prevented from becoming expensive.

  Furthermore, as described above, since the bent portion 84 of the scuff plate 80 is disposed close to the side portion of the sheet device 23, the gap between the side portion of the sheet device 23 and the scuff plate 80 can be reduced accordingly. Therefore, even when the passenger enters or gets into the passenger compartment 10 through the door opening 39 or during any work, even if the foot is placed on the scuff plate 80, mud or the like adhering to the feet passes through the gap. Intrusion is prevented.
