Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sleeve hole waterproof structure which can be safely constructed at a low cost, and can surely prevent intrusion of rainwater into the inside of a sleeve hole from the outdoor side.SOLUTION: A sleeve hole waterproof structure 1 includes a substantially cylindrical sleeve hole 2 penetrating an outer wall of a building, a primary waterproof lid 5 closing an outdoor side opening of the sleeve hole 2, and a secondary waterproof part 6 pressed into the inside of the sleeve hole 2. The secondary waterproof part 6 includes a substantially columnar body part 13 made of an elastic body which has a larger diameter than an inside diameter of the sleeve hole 2 and has a plurality of projecting rings 16 over the circumference of the circumferential direction.SELECTED DRAWING: Figure 1 【課題】安全且つ低コストで施工することができ、且つ、スリーブ孔の内部に屋外側から雨水が浸入することをより確実に防止することができるスリーブ孔防水構造を提供する。【解決手段】スリーブ孔防水構造１は、建物の外壁を貫通する略円筒形状のスリーブ孔２と、前記スリーブ孔２の屋外側の開口を閉じる１次防水蓋５と、前記スリーブ孔２の内部に押し込まれる２次防水部６と、を備え、前記２次防水部６は、前記スリーブ孔２の内径よりも大径の略円柱状であり、周回り方向の全周に突条環１６が複数設けられる弾性体から成る本体部１３を有する。【選択図】図１
