Abstract
Raw sewage, toilet paper or foreign matter is prevented from being stuck to an inner bowl of a stool by air bubbles. A cleaning mechanism of the stool comprises an outer cover which has an upper opening and can store cleaning liquid therein, an inner bowl accommodated inside the outer cover and a ring-shaped upper cover which contacts the upper end of the outer cover. An upper end peripheral edge of the inner bowl is spaced from the outer cover and upper cover and air is spouted from air discharge bodies provided at the bottom of the outer cover so that the air discharge bodies generate air bubbles which agitate the cleaning liquid so as to generate bubbles which stick to the entire surface of the inner wall of the inner bowl.
