<P>PROBLEM TO BE SOLVED: To provide a urinal capable of inhibiting urolith from developing in a drain lateral branch pipe while maintaining water saving capacity. <P>SOLUTION: A urinary comprises a trap part TP including a water storage part TPsu and a water storage part TPsw for storing water to form sealed water. The water storage part TPsu and the water storage part TPsw are formed side by side along a passage. The water storage part TPsu is configured in such a way that both the urine Ur received by a bowl part and washing water Wf supplied to the bowl part flows thereinto and flows out to a downstream side. The water storage part TPsw is configured in such a way that the urine received by the bowl part is hard to flow thereinto compared to the water storage part TPsu while the washing water Wf supplied to the bowl part flows thereinto and flows out to the downstream side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
