PROBLEM TO BE SOLVED: To surely support collision load of a side collision input into a rear portion of a side sill with a simple structure to disperse the collision load to a rear frame and a rear floor panel.SOLUTION: An FRP cabin is configured by connecting an inner skin 19 located at the vehicle interior side and an outer skin 20 located at the vehicle exterior side. The FRP cabin includes at least a rear floor panel 27, right and left rear side frames 23 extending in a longitudinal direction along right and left side edges of the rear floor panel 27, and a rear end cross member 24 connecting rear ends of the right and left rear side frames 23 and extending in a vehicle width direction along a rear edge of the rear floor panel 27. The inside of the rear side frames 23 is divided into an upper space 23a and a lower space 23b by a partition member 51, thereby enabling an increase of the heights of the rear side frames 23 and expansion of volume of a luggage room while securing rigidity of the rear side frames 23 and surely supporting collision load of a side collision with the partition member 51. |
