Abstract
Plates having a predetermined pattern are provided in each frame, side by side, at certain intervals along the longitudinal direction of the frame. A plurality of positioning holes, into which pins are inserted, are formed in each frame. A retainer portion is provided so as to extend from the inner periphery of each positioning hole and is plastically deformed when a pin is inserted thereinto. By inserting a pin into each positioning hole while a plurality of frames are stacked, the outer periphery of the pin contacts the retainer portion of each positioning hole. The retainer portion is deformed to correct misalignment among a plurality of plates.
