Abstract

PURPOSE: To make a cost for a mold inexpensive and to facilitate a work by a method wherein a plurality of projection-holding holes are bored on upper and lower plates of flat plates and a plurality of projections provided at upper and lower ends of a side plate are inserted into the holding holes and are fixed therto by twisting.
CONSTITUTION: A plurality of projection-holding holes 4 are bored on an upper plate 1 and a lower plate 3, each of them is of a flat plate, so as to coincide with an involute curve and a plurality of projections 5 provided at upper and lower ends of the side plate 2 are inserted into the holding holes 4 to fix the side plate 2 to the upper and lower plates with the projections by twisting them. According to this method, the upper plate 1 and the lower plate 3 may be formed by simple punching works while the side plate 2 may be formed by punching and bending works and a drawing work or the like is not necessitated, therefore, the cost for a mold becomes inexpensive while the manufacturing work thereof is facilitated.
