Claims

[Scope of utility model registration request]

In a stepping motor configured by welding and fixing two housings to each side of an annular plate of a core assembly, the annular plate of the core assembly has a plurality of parts on its outer periphery that are larger than the outer diameter of the housing. A stepping motor characterized in that a large protruding piece is integrally formed, and the housing and the annular plate are fixed by a fused portion formed by welding on the protruding piece.
