According to a bathtub drainage device and a replacing jig device thereof of the present invention, foreign materials remaining inside a filtering pipe filtering foreign materials in the case of water discharge from a bathtub can be easily and conveniently removed by taking out the filtering pipe as the filtering pipe can be separated from a water seal cup and fixated to a fixing flange to be taken in and out from the fixing flange by being locked inside the fixing flange. In addition, the water seal cup is coupled and fixated to the lower part of the filtering pipe with a filter unit to form a double pipe shape inside a body of a drain pipe. Accordingly, the bathtub drainage device is capable of efficiently maintaining the water seal without the foreign materials stuck between the filtering pipe and the water seal cup in the case of water discharge from the bathtub. Furthermore, an effect of easily and conveniently replacing and repairing the bathtub drainage device is obtained by separating the fixing flange components of the bathtub drainage device without dismantling the bathtub previously installed in a bathroom by using the replacing jig device of the bathtub drainage device, wherein the fixing flange components are exposed to the outside of the bathtub and are easily scratched, damaged, and corroded. |
