Abstract
In a damper housing structure body, an upper edge of a damper housing and a damper base are bonded by spot welding. The damper housing has a U-shape with an opening on a vehicle outer side in plan view, and includes a planar part in a corner between a front wall and an inner wall. The planer part includes plural welding spots arranged in the front-rear direction of the vehicle. Adjacent weld spots have mutually overlapping welding margins or an interval between two adjoining welding points is shorter than an outer diameter of the welding margins. One of the welding spots is welded while a current is applied to another welding spot that has been already welded. A current value for welding the one of the welding spots is higher than another current value for another one of the welding spots that has been already welded.
