。[Scope of Claim for Utility Model Registration] (1) A laminated iron core in which a plurality of plate-shaped iron cores are laminated and fixed by overlapping each other and caulking with a punch, the plate on the side from which protrusions are protruded by the caulking process. A laminated iron core characterized in that at least one of the ends of the shaped iron core is provided with an engagement hole corresponding to the shape of the projection. (2) The laminated iron core according to claim 1, wherein the tip of the protrusion protrudes from the engagement hole, and the amount of protrusion of the tip becomes an allowance for press-fitting the electromagnet into a coil bobbin or the like. (3) The laminated iron core according to claim 1, wherein the engagement holes are provided in a plurality of sheets and are gradually made smaller from the ends.
