         2 . The trap integrated drain device of  claim 1 , wherein the outer circumferential surface of the trap member ( 18 ) is spaced a predetermined distance from the inner circumferential surface of the trap casing ( 13 ) in a state in which the trap member ( 18 ) is mounted inside the trap casing ( 13 ) because the trap member ( 18 ) has an outer diameter less than an inner diameter of the tap casing ( 13 ), the mounting protrusions ( 19 ) are mounted on the stepped portion ( 17 ) in a state of protruding in an outward horizontal direction on the outer circumferential surface of the upper portion of the trap member ( 18 ), a portion of the trap member ( 18 ) on which each of the mounting protrusions ( 19 ) is disposed has an outer diameter corresponding to an inner diameter of an upper portion of the stepped portion ( 17 ) of the trap casing ( 13 ) so that the trap member ( 18 ) is installed vertically movable, a lower end of the drainpipe ( 5 ) disposed inside the trap member ( 18 ) is disposed on the upper portion of the trap member ( 18 ), which is spaced a predetermined distance from an inner bottom surface of the trap member ( 18 ), to allow water drained through the drainpipe ( 5 ) to be discharged in a zigzag manner between the trap casing ( 13 ) and the trap member ( 18 ) through a space between the trap member ( 18 ) and the drainpipe ( 5 ), and a plurality of foreign matter capturing protrusions ( 20 ) protrude upward at a predetermined distance on the upper end of the trap member ( 18 ). 
     
     
         3 . A trap integrated drain device for a washbasin, comprising:
 an upper fastener ( 2 ) having a ring shape in a horizontal direction and in which a drainpipe coupling hole ( 25 ) having a female screw part on an inner circumferential surface thereof is punched in a central portion of the upper fastener ( 2 ), and a tightening nut ( 12 ) is integrated with a lower portion thereof in a state of communicating with the drainpipe coupling hole ( 25 ) so that the upper fastener ( 2 ) is insert-coupled in a screw-coupling manner to a male screw part ( 6   b ) of the drainpipe ( 5 ) protruding downward by penetrating a lower protrusion part ( 4 ) of the washbasin ( 3 ) through the drainpipe coupling hole ( 25 ) and the tightening nut ( 12 ) to allow a sealing packing ( 11 ) disposed on a top surface of the upper fastener ( 2 ) to be fixed and coupled to a bottom surface of the lower protrusion part ( 4 ) of the washbasin ( 3 );   the sealing packing ( 11 ) having a ring shape, insert-coupled to an outer circumference of the drainpipe ( 5 ), and disposed on the top surface of the upper fastener ( 2 ) to come into close contact with the bottom surface of the lower protrusion part ( 4 ) of the washbasin ( 3 ) so that watertightness is maintained;   a barrel-shaped trap casing ( 13 ), of which an upper portion is opened and screw-coupled to the upper fastener ( 2 ), comprising an outlet ( 16 ) connected to the lower pipe ( 15 ) to vertically protrude downward; and   a barrel-shaped trap member ( 18 ), of which an upper portion is opened, comprising a plurality of mounting protrusions ( 19 ) that radially protrude from an outer circumferential surface of an upper portion thereof so as to be mounted on a stepped portion ( 17 ) disposed on an inner circumferential surface of the trap casing ( 13 ) and installed movable in a vertical direction, wherein a lower portion of the drainpipe ( 5 ) is disposed inside the trap member ( 18 ) through the opened upper portion of the trap member ( 18 ).   
     
     
         4 . The trap integrated drain device of  claim 3 , wherein a movement prevention protrusion wire ( 21 ) having a straight-line shape in a forward/backward horizontal direction protrudes upward from each of both left and right sides of the top surface of the upper fastener ( 2 ) so that a support plate ( 23 ) of a washbasin support ( 22 ) that supports the lower portion of the washbasin ( 3 ) is seated on the top surface of the upper fastener ( 2 ) to prevent the upper fastener ( 2 ) from moving by the left and right movement prevention protrusion wires ( 21 ), wherein the washbasin support ( 22 ) has a rod shape having a height corresponding to a distance between the washbasin ( 3 ) and the bottom surface, the support plate ( 23 ) that is laid in a horizontal direction is fixed and attached at a rear side of an outer surface of the upper portion of the washbasin support ( 22 ), the drainpipe ( 5 ) is penetrated and interposed together in a state in which the sealing packing ( 11 ) is disposed on a top surface of the support plate ( 23 ) because a through-hole ( 24 ) is punched in the support plate ( 23 ), and the upper fastener ( 2 ) is disposed to come into contact with a lower portion of the support plate ( 23 ) to allow the support plate ( 23 ) to be correspondingly insert-coupled between the left and right movement prevention protrusion wires ( 21 ) and tightly coupled through the tightening nut ( 12 ).
