A door leaf (10) for a railroad vehicle includes a tapping screw (40) penetrating a vertical frame and screwed into a prepared hole (30) provided in a horizontal frame while tapping the prepared hole (30), so that the tapping screw (40) can fasten together the vertical and horizontal frames. In the plane orthogonal to the axial direction of the tapping screw (40), the walls defining the prepared hole (30) in the horizontal frame are divided into a contact region (A1) where the prepared hole (30) touches the tapping screw (40) and a non-contact region (A2) where the prepared hole (30) does not touch the tapping screw (40).
