An odor back-flowing preventive structure of an erect toilet bowl comprises an exhaust valve for cleaning water(60) and an exhaust valve for easing nature. The exhaust valve for easing nature is opened and closed by opening and closing movement of the exhaust valve for cleaning water interposed in an inlet(51) of a flow path(50). In the exhaust valve for the easing nature, a penetration hole for discharging the washing water containing the easing nature flowing back from a toilet bowl(40) to an erect main exhaust flow path(20) is formed. The dome unit radially contacts the top of the obstacle tubular unit. In the inlet of the erected main exhaust flow path, a flow path(90) which is branched from the water supply unit and supplies the cleaning water is connected. The exhaust valve for the easing nature comprises a cap(31), a cylindrical hollow body(32) and a elastic hollow cap(34). |
