Abstract:
A laminated iron core includes a plurality of iron core pieces laminated each other, each iron core piece having a thickness of 0.2 mm or less. Each of the plurality of iron core pieces includes a flat part, openings and a pair of caulking protrusions opposed and separated from each other in plan view, each caulking protrusion having one end continuing with the flat part and the other portion being separated from the flat part to be inclined in a lamination direction of the iron core pieces. The pair of caulking protrusions of each iron core piece are fitted into the openings formed in an adjacent one of the plurality of iron core pieces in the lamination direction to join the plurality of iron core pieces, and the other ends of the pair of caulking protrusions face toward each other or face in opposite directions.
