PURPOSE: A drain valve of a washbowl is provided to prevent the leakage of the waste water through between a lever installation pipe and a second draining pipe by removing the gap between the lever installation pipe and the second draining pipe. CONSTITUTION: A drain valve of a washbowl comprises first and second drain pipes, a lever installation pipe(32), and a draining guide unit(100). The lever installation pipe is coupled with the first drain pipe and guides the ascending and descending of a lever following the pushing of a pressing valve. An opening and closing unit closes a first drain pipe for guiding the flow of waste water. The draining guide unit guides the waste water drained through the lever installation pipe to the second drain pipe. The draining guide unit accommodates the upper portion of the second drain pipe. |
