The present invention relates to a trap integrated drain device for a washbasin, which includes: an upper fastener having a ring shape in a horizontal direction, having a drainpipe penetration hole punched in a central portion thereof so as to be insert-coupled to an outer circumference of a drainpipe that protrudes downward by penetrating a lower protrusion part of the washbasin, and including a plurality of close-contacting protrusions radially protruding from a top surface thereof; a sealing packing having a ring shape, insert-coupled to the outer circumference of the drainpipe, and disposed on the top surface of the upper fastener to come into close contact with a bottom surface of the lower protrusion part of the washbasin by the close-contacting protrusions so that watertightness is maintained; a tightening nut disposed on the bottom surface of the upper fastener and screw-coupled to a male screw part of the drainpipe to allow the upper fastener and the sealing packing to be fixed and coupled to the bottom surface of the lower protrusion part of the washbasin; a barrel-shaped trap casing, of which an upper portion is opened and screw-coupled to the upper fastener, including an outlet connected to a lower pipe at a lower portion thereof to protrude downward; and a barrel-shaped trap member, of which an upper portion is opened, including a plurality of mounting protrusions that radially protrude from an outer circumferential surface of an upper portion thereof so as to be mounted on a stepped portion disposed on an inner circumferential surface of the trap casing and installed movable in a vertical direction, wherein a lower portion of the drainpipe is disposed inside the trap member through the opened upper portion of the trap member.
