Claims

[Scope of utility model registration request]

The cylindrical portion connected to the inner peripheral edge of the donut-shaped disk portion has pole teeth formed by forming irregularities arranged at a constant pitch in the circumferential direction, and the pole teeth are continuous to the outer peripheral edge of the donut-shaped disk portion. The yoke has an outer cylindrical part that protrudes toward the teeth, and a positioning recess is cut out in the edge of the outer cylindrical part, and the inner corner of the recess is recessed into the notch. A claw-pole stator yoke for a stepping motor, which is characterized by being curved.
