PURPOSE:To fix a shaft and sheet materials to each other highly accurately in dimensions and excellently in parallelism with simple construction, by providing projecting parts formed by moving shaft materials in the neighborhood of the sheet surface in the direction along the sheet material, to both sides of each sheet material of a shaft. CONSTITUTION:An anode plate 1' and a cathode plate 1 are alternately set at fixed intervals by a jig 20. A shaft 9 is inserted into a hole 1a which is an engaging part bored in the plate 1 and is a little larger in diameter than the shaft 9. Further, a relief hole 1'b having a space distance enough to insulate the shaft 9 is provided to a loose-fitting part of plate 1', and the shaft is loosely fitted to the hole 1'b. Caulking wedges 25, pressing means, are brought closer to the shaft 9 along the plate 1, as shown by an arrow mark at both faces of the plate 1 to press the caulking parts of shaft 9 between them in order to move the beefs of shaft 9 in the arrow P direction. The beef of shaft 9 pressed by the wedges 25 moves in the radial direction of shaft 9, and is formed into projecting parts to hold the plate 1 between them. |
