A connecting structure of a spring nut is provided to improve the workability of a screw by inserting a protruding jaw of the spring nut into a lower penetrating hole of a lower connecting hole. In a connecting structure of a spring nut(31), an upper penetrating hole(42) for penetrating a screw(9) is formed at an upper connecting unit(41). A lower penetrating hole(52) for penetrating the screw is formed at a lower connecting unit(51). A seating groove(53) is formed on the top surface of the lower connecting part. The spring nut is seated in the seating groove, and has an entry hole(32) coinciding with the lower penetrating hole and a protruding jaw(33) having screw threads inside.
