         6 . The dust collection device of  claim 5 , wherein the cover rib further includes a plurality of stop portions extending inward of a circumference of the cover rib from an inner circumferential surface of the plurality of teeth portions, respectively. 
     
     
         7 . The dust collection device of  claim 6 , wherein the protruding rib includes a stop groove recessed inward of a circumference of the protruding rib from an outer circumferential surface of the protruding rib, and the stop groove is configured to engage the plurality of stop portions while the opening/closing device is coupled to the support plate and the opening of the support plate is closed by the opening/closing cover. 
     
     
         8 . The dust collection device of  claim 1 , wherein
 the protruding rib has an elliptical shape or an arc shape, and   the cover rib has an arc shape.   
     
     
         9 . The dust collection device of  claim 1 , wherein the opening/closing cover is an elastic material including at least one of thermoplastic vulcanizate or silicon rubber. 
     
     
         10 . The dust collection device of  claim 1 , wherein the opening/closing device further includes a trap device on the upper surface of the opening/closing cover and that includes an attractant or an adhesive material. 
     
     
         11 . The dust collection device of  claim 1 , wherein the opening/closing device further includes a trap device on the upper surface of the opening/closing cover and that includes a plurality of wires which cross each other in a grid pattern. 
     
     
         12 . The dust collection device of  claim 10 , wherein the trap device is positioned inward of a circumference of the cover rib. 
     
     
         13 . The dust collection device of  claim 1 , wherein the opening/closing device further includes a trap device on a lower surface of the opening/closing cover and that includes a fluorescent material or a luminous material. 
     
     
         14 . The dust collection device of  claim 13 , wherein the trap device extends along an edge of the lower surface of the opening/closing cover. 
     
     
         15 . A dust collection device, comprising:
 a support plate including an opening through which dust is introducible;   a protruding rib extending downward from a circumference of the opening of the support plate; and   an opening/closing device couplable to the support plate, and   wherein the opening/closing device includes:
 an opening/closing cover configured to open and close the opening of the support plate, while the opening/closing device is coupled to the support plate, and 
 a rib groove recessed from an upper surface of the opening/closing cover and configured so that the protruding rib is inserted in the rib groove while the opening of the support plate is closed by the opening/closing cover. 
   
     
     
         16 . The dust collection device of  claim 15 , wherein the opening/closing device includes a stopper surrounding the rib groove. 
     
     
         17 . The dust collection device of  claim 15 , wherein the rib groove has an arc shape. 
     
     
         18 . The dust collection device of  claim 15 , wherein the opening/closing cover is an elastic material including at least one of thermoplastic vulcanizate or silicon rubber.
