THREADABLY ENGAGED PART STRUCTURE OF SCREW, AND FIXING STRUCTURE OF FIXED MEMBER
To provide a threadably engaged part structure of a screw which is improved in water cut-off performance.SOLUTION: A threadably engaged part structure of a screw that is threadably engaged with a wooden part covered with a waterproof sheet has an interposition member interposed between the waterproof sheet and the wooden part, in which the screw has an enlarged diameter part having a diameter larger than a screw outer diameter on a side closer to the head part side than the screw part formed with a screw thread, and a crossing surface crossing an axial direction of the screw part in a boundary part between the screw part and the enlarged diameter part, and the crossing surface presses the waterproof sheet and the interposition member against the wooden part side in a state of being threadably engaged with the waterproof sheet and the interposition member while penetrating therethrough.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木質部との間に介装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、前記防水シートと前記介装部材とを貫通して螺合された状態で前記交差面が前記防水シートと前記介装部材とを前記木質部側に押圧している。【選択図】図３
