A roof side rail has a closed cross-section formed by integrating side rail outer and inner, and a part of the side rail forms an upper edge of a vehicle body side opening. A pipe-shaped reinforcing member is inserted into the side rail from the front side thereof to a part forming the upper edge of the opening, and is fixed to the side rail inner. Therefore, even when cross-sectional areas between the front side of the side rail and the part of the side rail forming the upper edge of the opening differ, both of which are connected to each other via a step part deviated to the largest degree, the stiffness of the step part is increased, and the number of parts and man-hours required for welding are reduced.
