PROBLEM TO BE SOLVED: To provide a drain structure capable of maintaining sufficient strength, while facilitating connecting work of pipes for draining from a washer pan. SOLUTION: This drain structure 1 has a waterproof receiving base 2, a drain trap 3 stored in an opening part 2b bored in a part of the receiving base 2, and a storage part 4 having a storage space 4b of the pipes 6 and 10 for rotatably supporting the drain trap 3 around a vertical shaft and connected to the drain trap 3. The drain structure is constituted so that the storage part 4 is arranged on a floor; the drain trap 3 is connected to an existing drain pipe 7 fixed under the floor by the storage space 4b of the storage part 4; the receiving base 2 is placed from above the storage part 4; and the drain trap 3 is stored in and fixed to the opening part 2b bored in a part of the receiving base 2. Even if a position of the drain pipe 7 is fixed, the drain structure can be easily assembled via the storage space 4b. A pipe having predetermined rigidity can be used, and a highly strong pipe structure can be provided. COPYRIGHT: (C)2006,JPO&NCIPI
