Abstract

The invention provides a door band course structure to improve relative fore-and-aft force reforming strength of door band course without adding weight, which is characterized by the following: setting strength component 16 along door band course 14 of front side entrance12; observing dent base of the strength component 16 along door band course from up-and-down direction of car body to display bending shape of fore-and-aft direction toward car broad inside projection; observing dent top of the door inside plate 24 along door band course from up-and-down direction of car body to display bending shape of fore-and-aft direction toward car broad inside projection; Hence, the centroidal P of closed cross-sectional structure 36 containing door inside plate 24 and strength component 16 bends projection shape toward inside car along the door band course.
