A step portion that is farther toward a vehicle width direction outside than a cabin inside vertical wall portion, is set on a door inner panel. A portion of the step portion is a first overlapping portion that is arranged in a position overlapping with an outside vertical wall portion of a center pillar in a vehicle side view. A portion of the outside vertical wall portion of the center pillar is a second overlapping portion that faces the first overlapping portion at a distance that is narrower than a distance between the step portion and the cabin inside vertical wall portion. A third overlapping portion that is connected to the first overlapping portion in a position overlapping with the second overlapping portion of the center pillar in the vehicle side view, is set on an end portion of a beltline reinforcement in a length direction thereof.

Vehicle side structure

A vehicle front structure includes a roof header, which is arranged on a lower side of a front part of a roof panel of a vehicle in a longitudinal direction of the vehicle, and extends in a vehicle width direction, and a rear wall part, which is provided in the roof header, and extends towards the roof panel on the rear side of the roof header. The roof header is provided with a region in which a length of the roof header in a front-rear direction of the vehicle is longer than that of a surrounding area, and height of the rear wall part is smaller than that of the surrounding area.

Vehicle front structure

A vehicle structure body includes roof side railsthat extend in the longitudinal direction of a vehicle on both sides in a vehicle width direction, and center pillarsthat are connected to rear end portionsof the roof side railsand extend in a vertical direction of the vehicle. The cross-sectional area of the roof side railis substantially constant from the front end of the roof side railto a front position P in front of the center pillar, and the cross-sectional area of the roof side rail is reduced from the front position P to a position S immediately before a joint portion between the roof side railand the center pillar. When a collision load acts on the roof side rail, the roof side railis easily folded at a portion of which the cross-sectional area is reduced. Accordingly, it is possible to reduce the input of moment to the center pillar
