PURPOSE:To completely eliminate the necessity of work for adjusting a shaft core, by means of inserting engagement parts of cylindrical pattern of the support substance to each other in such manner with a positioning concentrically made between the center of wire electrode guide and the shaft of eccentricaly operating disk. CONSTITUTION:An eccentrically operating disk 5 is coupled coaxially to an impeller 9 as a driven unit through a shaft 8, and the shaft 8 is rotatably supported by a plate substance 11 through a bearing 10. To a mounting board 12, secured to a wire guide 4, is installed a support plate 13 by a screw 14, with a cylindrical room portion 15 provided in the support plate 13, and its top end portion constructs a first engagement part 17 of cylindrical shape concentrically located with an axial line 16 that connects guide centers 4', 7' of the both guides 4, 7. In a bottom end part of the plate substance 11, is provided a second engagement part 18 of cylindrical shape concentrically positioned with a center of the disk 5, thus for a setting work of the disk 5, the both engagement parts 17, 18 are engaged. |
