SCREWING PART STRUCTURE OF SCREW AND FIXING STRUCTURE OF FIXED MEMBER
To provide a screwing part structure of screw with better cut-off performance, and others.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 is provided with an enlarged diameter part with a diameter larger than a screw outer diameter, nearer to the head than a screw part in which a screw thread is formed, and an intersecting face for intersecting the axial direction of the screw part, in a boundary between the screw part and the enlarged diameter part. The screw penetrates through the interposing member and the waterproof sheet, and in a screwed state the intersecting face compresses the interposing member to the wood part side.SELECTED DRAWING: Figure 3
【課題】より止水性に優れたねじの螺合部構造等を提供する。【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、ねじ山が形成されているねじ部よりも前記頭部側にねじ外径よりも大きな直径をなす拡径部と、前記ねじ部と前記拡径部との境界部に前記ねじ部の軸方向と交差する交差面と、を有し、前記介装部材と前記防水シートとを貫通しており、螺合された状態で前記交差面が前記介装部材を前記木質部側に圧縮している。【選択図】図３
