PROBLEM TO BE SOLVED: To provide a terminal screw elevating mechanism, capable of forming a compact terminal part by reducing the height of the terminal part by disposing a coil spring to elevate a terminal screw in parallel with a terminal screw chamber. SOLUTION: The terminal screw elevating mechanism, has the terminal part, formed by mounting a terminal plate 3 to a case 1 of an insulating material and mounting the terminal screw for fixing the crimp terminal of wiring, by fastening it to the terminal plate 3, a coil spring storage chamber is formed in the case 1 adjacently to a screw chamber by interposing a spring receiving plate 8, so as to be interposed between the terminal plate 3 and the head part of the terminal screw 4 in the screw chamber inside the housing 1, and a spring- receiving pieces 8a, with which the upper part of the coil spring 9 stored in the coil spring storing chamber is brought into contact, is connectively provided at the one end of the spring receiving plate 8. On the side where the spring receiving piece 8a is connectively provided in the spring receiving part 8 and on the side facing the spring-receiving piece 8a, elevating guide pieces 8b, 8c brought into sliding contact with the wall surface of the spring chamber are formed respectively.
