The present invention addresses the problem of providing a door leaf for a railway vehicle, which is easy to manufacture, a fastening structure, and a method for manufacturing a door leaf for a railway vehicle. The door leaf for the railway vehicle is provided with a self-tapping screw, and the self-tapping screw is screwed into a bottom hole (30) formed in the transverse frame while penetrating through the vertical frame and tapping the bottom hole (30), so that the vertical frame and the transverse frame are fastened. The wall of the lateral frame forming the bottom hole (30) has a contact region (A1) in contact with the self-tapping screw in a plane orthogonal to the axial direction of the self-tapping screw, and a non-contact region (A2) not in contact with the self-tapping screw.
本发明的课题在于提供一种容易制造的铁道车辆用门扇、紧固构造和铁道车辆用门扇的制造方法。铁道车辆用门扇具备自攻螺钉,该自攻螺钉一边贯穿纵框而对设置到横框的底孔(30)进行攻丝一边向该底孔(30)拧入,从而将纵框和横框紧固。横框的形成底孔(30)的壁具有在与自攻螺钉的轴向正交的面中与自攻螺钉接触的接触区域(A1)和不与自攻螺钉接触的非接触区域(A2)。
