To provide a screwing part structure of screw with better cut-off performance.SOLUTION: A screwing part structure of a screw that is screwed to a wood part covered with a waterproof sheet is provided with an interposing member that is interposed between the waterproof sheet and a head of the screw and that abuts on the waterproof sheet. The screw penetrates through the interposing member and the waterproof sheet and the interposing member presses the screw for penetrating through the interposing member, from the outer peripheral side.SELECTED DRAWING: Figure 3
【課題】より止水性に優れたねじの螺合部構造を提供する。【解決手段】防水シートで覆われた木質部に螺合されているねじの螺合部構造であって、前記防水シートと前記ねじの頭部との間に介装されて前記防水シートに当接される介装部材を有し、前記ねじは、前記介装部材と前記防水シートとを貫通し、前記介装部材は、貫通している前記ねじを外周側から押圧している。【選択図】図３
