PROBLEM TO BE SOLVED: To eliminate a bubbling sound at cleaning finishing time by arranging an air intake pipe on the reverse side of a back face joining piece (a cover) of a spreader chamber arranged above a urinal, and sucking air in the spreader chamber at wash water flowing-down time. SOLUTION: Air tries to enter a spreader chamber 2 from a cleaning hole 4 at cleaning finishing time when wash water in the spreader chamber 2 of a urinal 1 is wholly made to flow down from the cleaning hole 4, and at this time, the air flows in the spreader chamber 2 from an air hole 8 of an air intake pipe 6d. A bubbling sound by the inflow of the air from the cleaning hole 4 is eliminated. When the spreader chamber 2 is put in a state of being filled with the wash water, the wash water is made to flow downward from the upper end side of the air hole 8 of the air pipe 6d to flow down in a toilet bowl so that the water does not blow out to the front side of the urinal 1. An air intake hole can be formed even in a toilet bowl having no rim on the front side to thereby easily manufacture the urinal generating no bubbling sound.
