Laminated core for rotary electric machine, and rotary electric machine

A laminated core for a rotary electric machine, comprising:

• a first core member including a plurality of first core pieces each having a back yoke and a magnetic pole tooth protruding inward in a radial direction from the back yoke, the back yoke having a projecting end which has a connection portion at one end in a first circumferential direction, and having a recessed end at another end in a second circumferential direction, the first core member being formed by arranging the plurality of first core pieces while fitting the projecting end of each first core piece and the recessed end of the adjacent first core piece;
• and
• a second core member including a plurality of second core pieces each having a back yoke and a magnetic pole tooth protruding inward in the radial direction from the back yoke, the back yoke having a projecting end which has a connection portion at one end in the second circumferential direction, and having a recessed end at another end in the first circumferential direction, the second core member being formed by arranging the plurality of second core pieces while fitting the projecting end of each second core piece and the recessed end of the adjacent second core piece, wherein
• a member including the first core member and a member including the second core member are stacked while the projecting ends of the first core pieces and the projecting ends of the second core pieces are overlaid in an axial direction and connected rotatably by the connection portions, and
• when the laminated core is formed in an annular shape, a radially inner part of a contact surface formed by the projecting end of the first core piece and the recessed end of the first core piece that are adjacent in a circumferential direction, and a radially inner part of a contact surface formed by the projecting end of the second core piece and the recessed end of the second core piece that are adjacent in the circumferential direction, are respectively positioned in a plane including a center axis of the annular stacked core.
