PROBLEM TO BE SOLVED: To provide a structure of a sink capable of properly selecting the size of a drain port without so reducing the effective use area of the sink due to the shape of a drain groove and smoothly flowing a drain in the center direction (direction of the drain port) in the drain groove due to a difference in water level produced due to the shape of the drain groove. SOLUTION: The bottom part 2 of the sink 1 has a tilted surface 9 tilting downward from the front side to the bottom side 7 and led to a bottom wall surface 8. The drain groove 3 extending to the center part and gradually enlarged at the bottom part is formed in the tilted surface 9 along the base of the bottom wall surface 8. A recessed part 10 is formed in the enlarged part 4 of the drain groove 3. The drain port 5 is formed at the recessed part 10. COPYRIGHT: (C)2007,JPO&INPIT
