PURPOSE:To surely and stably perform positioning, in the structure of an ionizing frame for providing an ionizing wire under tension, by providing a notched recessed part to a frame edge part and positioning the spring providing the ionizing wire under tension at the apex of the notched recessed part. CONSTITUTION:An ionizing wire 11 is provided to an ionizing frame 15 through a spring 12. Herein, a V-shaped notched recessed part 13 is formed to the edge part of the ionizing frame 15 and the spring 12 is positioned at the apex of this V-shaped structure and hooked with a hooking hole 14 to mount the ionizing wire 11. By this method, the spring 12 is not moved left and right, and the mounting thereof becomes easy. Therefore, the discharge distance between the ionizing wire 11 and a dust collection electrode plate is stabilized to exhibit good capacity. |
