An arrow view is shown. As shown in the figure, the pillar 21 is a pillar member in the vertical direction of the vehicle.
The gusset 22 is connected to the rail member mounting portion of the pillar 21. Rails 23 serving as rail members are respectively coupled to the sides of the gussets 22, and the rails 23 extend in a direction perpendicular to the pillars 21 (the front-rear direction of the vehicle). The pillar 21 and the rail 23 have a mountain-shaped open cross-sectional shape. The gusset 22 has a pillar fitting portion 24 that fits along the outside of the pillar 21, and the gusset 22 has the rail 23 positioned laterally. The rail mounting portions 25 to be fitted to each other are formed. The pillar fitting portion 24 and the rail mounting portion 25 are substantially cross-shaped
