A drain trap for preventing stink in an apartment house is provided to operate easily by opening and closing an upper part of a drain pipe with turning a handle, and to prevent stink by restricting sewage from flowing backward through a drain port. A drain trap includes an upper case(10) installed on a drain pipe(2), a lower case(20) thread-connected to the upper case, installed in a floor and connected to the drain pipe, an upper cap(30) arranged in an upper center of the upper case, a lower cap combined with a lower part of the upper cap, a connector(50) assembling the upper cap with the lower cap to protrude a lower elastic ball outward, and an inner cover combined with a lower part of the connector and moved up and down in lifting up and down the connector. A handle part(52) is formed in an upper part of a bolt part in the connector. The inner cover is lifted up by turning a handle, and sewage is discharged to the drain pipe between the inner cover and a central drain pipe. |
