PROBLEM TO BE SOLVED: To certainly prevent occurrence of stain on an entire bowl surface by providing the stool bowl surface coated with a water repellent coating and a plurality of water delivery holes over the bowl surface, and setting a relation between an interval between the water delivery holes and a minimum diameter of the water delivery holes in a predetermined range. ;SOLUTION: A bowl surface 1 of this closet bowl A is coated with a water repellent coating, and a rim portion 3 over the bowl surface 1 of the closed bowl A has a plurality of water delivery holes 2. When an interval between the water delivery holes 2 is assumed d, and a minimum diameter of the water delivery holes 2 is assumed r, d and r meet a relation 0.5d/r1.5. When a cleaning operation for the closet bowl A is performed, a water feed valve opens to inject clearing solvent from the plurality of water delivery holes 2. Because the interval between the water delivery holes is sufficiently short at this time, the clearing solvent goes over the entire stool bowl surface, and a stain-proof effect provided by the water repellent coating is applied to the entire bowl surface. Therefore, occurrence of stain of the entire bowl surface can be certainly prevented.;COPYRIGHT: (C)2001,JPO
