PROBLEM TO BE SOLVED: To provide a laminated iron core for a rotary electric machine capable of enlarging an interval between core pieces without re-evaluating magnetic characteristics.SOLUTION: A tabular core piece 13 comprises a back yoke part 14 and a magnetic pole teeth part 15. In each of first core members 21 and 22, a plurality of tabular core pieces 13 are arrayed in a band shape in such a manner that protrusions 16 and recesses 17 of the back yoke parts 14 are adjacent, laminated and connected in an axial direction B and in the lamination in the axial direction B, the protrusions 16 are arrayed in the same direction as a rotation direction C of a rotary electric machine. In a second core member 23, the protrusions 16 are arrayed in a reverse direction. A plurality of first core members 21 and 22 and second core members 23 are laminated alternately. The protrusions 16 of the core pieces 13 in a pair of the first core member 22 and the second core member 23 at an upper layer side include rotation hole parts 27 and 28 into which a rotation pin 30 can be inserted. The first core member 21 includes a coupling part 25 for coupling the back yoke parts 14 of the neighboring core pieces 13 at an outer diameter side than the protrusions 16 and the recesses 17. |
