Abstract

Provided is an upper body structure for a vehicle that can reduce displacement of a roof side rail in the event of a side collision and thereby restrain a pillar from moving into a vehicle cabin. Theupper body structure includes: a pair of left and right roof side rails 10 coupled to respective ends of a roof panel 3 in a vehicle width direction and extending substantially in a vehicle front-reardirection; and a roof reinforcement 30 configured to couple intermediate portions in the vehicle width direction of the pair of roof side rails 10. A vehicle-width-direction inner side end of each roof side rail 10 is substantially formed in a concave-convex shape in side view, a vehicle-width-direction outer side end of the roof reinforcement 30 is substantially formed in a concave-convex shapein side view, and the concave-convex shaped end of each roof side rail 10 and the concave-convex shaped end of the roof reinforcement 30 are disposed so as to intersect with each other in side view.
