PROBLEM TO BE SOLVED: To provide water draining equipment of a sink allowing a user to clean a water draining device and a net cage stored in its inside easily without requiring a complicated mechanism for cleaning. SOLUTION: In this water draining equipment of the sink 12 having the water draining device 16, a water draining trap 26 is composed of a main trap part 28 on the upstream side having fixed height of overflowing fringe P and a water sealing height movable part 30 on the downstream side more than the main trap part 28 and moving height of water sealing in the water draining trap 26 vertically. The water sealing height movable part 30 collects drainage in a movable tube 36 as a damming-up part by moving the movable tube 36 upward, collects water in the water draining device 16 by setting height of water sealing to a position being higher than a flow-out port 22, and making the height of water sealing equal to the overflowing fringe P in the main trap part 28 by moving the movable tube 36 downward to drain the drainage from the water draining device 16.
