PURPOSE: A bolt coupling structure is provided to stably couple a panel with parts without wearing a screw section of a nut member and twisting a restriction pin by preventing the restriction pin from directly making contact with the screw section of the nut member. CONSTITUTION: A bolt coupling structure(100) includes a nut member(10), a restriction pin member(20), and a pressing member(30). The nut member(10) is coupled to one side of a panel(11) and has a small diameter section and a large diameter section. The restriction pin member(20) is inserted into the large diameter section of the nut member(10). The pressing member(30) is installed at one end of the restriction pin member(20) so as to press the nut member(10) towards the panel(11). The nut member(10) coupled to one side of the panel(11) has a hollow section. The restriction pin member(20) restricts a position of the nut member(10) with respect to the panel(11).
