PURPOSE: A drain trap is provided to easily clean a hanging member of an assembly unit because the assembly unit can be easily assembled and disassembled in/from a valve housing. CONSTITUTION: A drain trap comprises a valve housing(110), a single assembly unit, a silicon odor cutoff valve(140), and an opening and closing device. The top and bottom of the valve housing are opened. The valve housing has a deodorizing and coupling space(111a) and a coupling protrusion(111b). A popup head(130), an actuating member(131), and a filter member are assembled in the single assembly unit. The silicon odor cutoff valve is formed in an annular shape. The inner surface of the odor cutoff valve touches the outer surface of a cylinder member of the popup head, and the outer surface is attached to the inner circumferential wall(112) of the valve housing. The opening and closing device is installed inside the filter member and opens and closes a lowermost drain of the valve housing when the popup head is pressed. |
