摘要： PROBLEM TO BE SOLVED: To prevent external fluid from flowing back through a drain pipe and entering a floor drain funnel.SOLUTION: A cylindrical body 21 is screwed and fixed to the upper end part of the drain pipe 17. Inside the cylindrical body 21, a valve seat member 22 comprising an annular part 22a fitted and fixed to the inner periphery of the cylindrical body 21 and a straight part 22b for crossing the center part of the annular part 22a in the radial direction is provided. Inside the cylindrical body 21 on the lower side of the valve seat member 22, a pair of valve bodies 23 and 24 in a semicircular shape are provided so as to be turned between a closed position and an open position. When positioned at the closed position, the pair of valve bodies are in press contact with two parts when the valve seat member 22 is divided into two at the center in the width direction of the straight part 22b respectively and close the inside of the cylindrical body 21. When positioned at the open position, the pair of valve bodies are separated downwards from the valve seat member 22 and open the inside of the cylindrical body 21, The valve seat members 23 and 24 are turned and energized from the open position side to the closed position side by a torsional coil spring 26 and positioned at the closed position.
