1. A step device comprising: a step housing having a box shape;guide rails mounted on both sides of the step housing;step rails coupled to the guide rails to move along the guide rails; anda scaffold coupled to the step rails and moving along the guide rails through the step rails to be received in
1. A step device comprising: a step housing having a box shape;guide rails mounted on both sides of the step housing;step rails coupled to the guide rails to move along the guide rails; anda scaffold coupled to the step rails and moving along the guide rails through the step rails to be received in the step housing or drawn to an outside of the step housing,wherein in the guide rails, an upper wall, a first side wall and a lower wall are integrally consecutively connected and a second side wall facing the first side wall is opened, to form a consecutive channel in a longitudinal direction,wherein a drain path is formed inside the channel around a lower guide jaw,wherein a drain surface is formed outside the channel,wherein the drain path has a dented shape, andwherein the drain surface is inclined downward to the outside of the channel. 2. The step device of claim 1, wherein the step housing has a quadrangular box shape. 3. The step device of claim 1, wherein the step housing is fixedly mounted on a vehicle body via a mounting bracket having an L-shape. 4. The step device of claim 1, wherein a hole is formed on a top of the step housing and a power supply line is inserted through the hole to supply external power into the step housing. 5. The step device of claim 1, wherein: the step rails are inserted into the channel to be guided. 6. The step device of claim 5, wherein: the lower guide jaw which is uplifted in a height direction and on which a guide roller is seated to rollably move is formed on a top in the height direction of the lower wall of the guide rail, anda guide surface which the guide roller closely contacts to rollably move is formed on a bottom of the upper wall facing the top of the lower wall. 7. The step device of claim 6, wherein: one or more through drain holes are formed on the drain path. 8. The step device of claim 6, wherein: a step jaw which is stepped with respect to the guide surface is formed on the bottom of the upper wall, andan extension flange which is suspended on the step jaw and a side of the guide jaw to restrict movement in a width direction is provided at the guide roller. 9. The step device of claim 1, wherein: the step rail has a quadrangular box shape in which a length is larger than a width thereof,one or more assembly holes are formed to pass through a top and a bottom in a height direction of the step rail at a predetermined interval in a longitudinal direction, anda guide roller is inserted into each assembly hole to be rotatably fastened with an assembly pin. 10. The step device of claim 9, wherein a bush is assembled by engaging in an outer periphery of the assembly pin. 11. The step device of claim 9, wherein: multiple fastening holes are formed on the step rail at a predetermined interval in the longitudinal direction,the multiple fastening holes are formed on both sides of the step rail, anda fastening pin is inserted into each fastening hole to be integrally fixedly fastened to the scaffold. 12. The step device of claim 11, wherein: the scaffold has a quadrangular plate shape, andmultiple reinforcing ribs are formed to protrude from one side at a predetermined interval in the longitudinal direction of the scaffold. 13. The step device of claim 12, wherein: assembly bosses having an arc-shaped cross-section are integrally formed at a portion of the multiple reinforcing ribs, andmultiple fastening pins that pass through the step rail are inserted into and fastened to the assembly bosses. 14. The step device of claim 1, wherein a plug that seals an inside of the step rail is coupled to one fore-end of the step rail in a longitudinal direction while engaging in the step rail. 15. The step device of claim 9, wherein: the guide roller, the step rail and the assembly pin are all deployed in the guide rail.
