Claims

[Scope of utility model registration request]

In a motor laminated core in which a plurality of thin core members are laminated, one of the outer thin core members of the plurality of thin core members has a thickness that exceeds the thickness of the other thin core members when laminated. A long cylindrical protrusion is provided, a hole for penetrating the protrusion is provided at a position corresponding to the protrusion on another thin iron core member, the protrusion is passed through the hole, and the tip of the protrusion is caulked. Or an electric motor laminated core characterized by being integrally fixed by press-fitting.
