The drain trap body includes a supporter which is disposed at the outer circumference of a drain hole of the lower part of the drain trap body and a slope part and a retaining jaw which are formed on the inner face of the front end of the supporter. The drain trap supporter has a guide protruding member disposed between the upper side and a protrusion part, such that the retaining jaw of the supporter is guided and retained. On the outer face of the auxiliary sleeve, an elevation groove is formed in the longitudinal direction to be fit to a protrusion pin of the upper part of the inner wall of the drain trap body, and a retaining groove is formed in the circumferential direction. The drain trap according to the present invention is easy in manufacturing and assembly and is convenient in adjustment of expansion and installation of the drain trap. Moreover, the drain trap is conveniently carried and stored because it is small in volume. |
