PURPOSE: A nut connecting method is provided to conveniently and promptly assemble a chassis and to obtain a firm assembled structure by making assembling completed by simple insertion of a nut into a guide groove of the chassis. CONSTITUTION: An insertion groove(103) is formed in a portion of a guide groove(102) of a chassis(101) to insert a portion of a nut(111). To rotate the nut in the insertion groove, a portion of the insertion groove is expanded into first and second expansions. A chamfering face(106) is formed in an opening of the guide groove to let a corner f the nut guided into the guide groove. An auxiliary groove is formed in the guide groove to make a corner of the nut entering the guide groove by the chamfering face rotate in the guide groove. Another auxiliary groove(108) is formed in the guide groove to make the other corner of the nut rotate in the guide groove. An auxiliary groove expansion(109) is formed in one auxiliary groove to rotate the nut in the guide groove in horizontal to the bottom face of the guide groove. With the grooves and expansions guiding the nut for optimal insertion of the nut into the guide groove, a chassis is assembled by simple fitting of the nut into the guide groove.
