Abstract: A urinal for receiving and discharging urine having a bowl portion having a bowl surface for receiving urine; a spouting device disposed on a top portion of the bowl portion for spouting flush water onto the bowl surface; and a discharge trap portion, communicating with a discharge port disposed on a bottom portion of the bowl portion, for discharging flush water and forming a water seal on a downstream side of the bowl portion. The discharge trap includes a descending conduit, a horizontal conduit, and an ascending conduit, and a cross section perpendicular to a discharging direction of either the horizontal conduit or the ascending conduit on the discharge trap portion is formed so that an inner side of the urinal from a center of the cross section has a smaller cross sectional area than an outer side of the urinal from the center of the cross section.

Abstract: A urinal capable of suppressing the flow speed differential between the flow speed of flush water flowing into the front side of an ascending pipe and the flow speed of flush water flowing into the back side thereof, and of suppressing the occurrence of stagnation in the flow of flush water, and of suppressing the occurrence of uric scale. The urinal having a discharge trap including a horizontal pipe; a top portion of horizontal pipe is formed by a return flow path-forming portion at the bottom end of the shared wall; and a resistance portion for slowing the flow speed of flush water flowing in the vicinity of this bottom portion is formed at the bottom portion of the horizontal pipe.
