PROBLEM TO BE SOLVED: To easily stretch and lay a grid wire on a shielding case with predetermined tension in a scorotron type electrifying device using the grid wire. SOLUTION: Almost middle parts of the side walls 10a and 10b of the shielding case 1 are respectively extended outward. Next, the grid wire 3 is alternately laid over a plurality of pins 13, and is stretched over the upper aperture 11 of the shielding case 1. Then, the side walls 10a and 10b are restored to an initial state, and the grid wire 3 laid over the upper aperture 11 of the shielding case 1 is tensioned. COPYRIGHT: (C)2007,JPO&INPIT
