The foreign substance filtering unit is located at a lower side of the cap, by installing the cap on the upper part of the body as being installed inside the upper part of the body separated from the cap as being detachable, and filters the foreign substances included in the sewage flowing into the body whose top is opened by the cap. According to the present invention, the foreign substance filtering unit prevents a drainage hole from being blocked by filtering foreign substances such as hair included in the drained water by a foreign substance filtering member, when the water is drained from the drainage hole of the sink through the body by opening of the cap. The foreign substance filtering member filtering the foreign substances can be installed and separated easily for maintenance and replacement.
