To provide a waterproof pan drainage structure capable of preventing overtightening or insufficient tightening of a tightening member and making an angular position of the tightening member constant when tightening is completed.SOLUTION: A drain trap is fixed to a peripheral edge of a drain opening formed in a waterproof pan by a tightening member, and comprises a first cylindrical portion inserted into the drain opening, and an annular receiving portion along a lower surface of the peripheral edge of the drain opening. The tightening member has a second cylindrical portion inserted into the first cylindrical portion of the drain trap, and a flange portion along an upper surface of the peripheral edge of the drain opening. When the tightening member rotates in the tightening direction, a guide protrusion formed on an inner periphery of the first cylindrical portion guides an engagement protrusion formed on an outer periphery of the second cylindrical portion, so that the tightening member approaches the drain trap, and the peripheral edge of the drain opening is sandwiched between the flange portion and the receiving portion. Further, a locking projection is formed on the first cylindrical portion, and when the engagement projection of the tightening member hits the locking projection, rotation of the tightening member in the tightening direction is prohibited.SELECTED DRAWING: Figure 4
【課題】締付部材の過剰締め込みや締め込み不足を防止することができ、締め込み完了時の締付部材の角度位置を一定にすることができる防水パンの排水構造を提供する。【解決手段】防水パンに形成された排水用開口の周縁部に、排水トラップは締付部材により固定され、排水用開口に挿入される第１筒部と、排水用開口の周縁部の下面に沿う環状の受部とを有し、締付部材は排水トラップの第１筒部に挿入される第２筒部と、排水用開口の周縁部の上面に沿うフランジ部とを有している。締付部材が締め付け方向に回動すると、第１筒部の内周に形成されたガイド突起が、第２筒部の外周に形成された係合突起を案内することにより、締付部材が排水トラップに近づき、フランジ部と受部とで排水用開口の周縁部を挟持する。さらに、第１筒部には係止凸部が形成されており、この係止凸部に締付部材の係合突起が当たることにより、締付部材の締め付け方向への回動が禁じられる。【選択図】図４
