PROBLEM TO BE SOLVED: To provide a drain trap which prevents a drain hose from slipping out of a hose joint even if hydraulic pressure is applied to drainage such as in forced drainage. SOLUTION: The drain trap is set and inserted into a drain pipe C opening to a floor surface, and formed of: a drain trap main body 1 for intercepting odors by water-sealing by means of residual drainage; a drain trap main body receptacle 4 supporting the drain trap main body 1; the hose joint 6 connected to the drain trap main body receptacle 4; and a packing holder 5 engaging with a tapered flange formed on the hose joint 6, and connecting the hose joint 6 to the drain trap main body receptacle 4. Then a joint portion of the hose joint 6 to which the drain hose 8 is connected, has formed therein a fitting portion 6b to which a bellows portion 8a is fitted, and the joint portion between the hose joint 6 and the drain hose 8 are tightly constricted by a hose band fixture 7, to thereby connect the drain hose 8 to the hose joint 6.
