DOOR SASH

摘要

When a formed product having undergone roll forming and welding is bent in the shape of a door sash, the formed product may distort and/or deform. Such distortion and/or deformation is reduced to a sufficient degree. A door sash is formed by bending an elongated metal plate in a widthwise direction such that portions thereof are superimposed, which are welded together for unification. The door sash has a joint portion extending in a longitudinal direction and having exposed surfaces extending continuously in the widthwise direction, a pocket portion extending continuously from one widthwise end of the joint portion and being to be located on the inner side of a vehicle, and a design portion extending continuously from the other widthwise end of the joint portion and being to be located on the outer side of the vehicle. The door sash is bent in the longitudinal direction, and has two parallel welding marks formed on each of the exposed surfaces of the joint portion and extending in the longitudinal direction.
