Claims

[Scope of utility model registration request]

A rotor body that is provided at a longitudinally intermediate portion of a shaft and rotates integrally with the shaft due to the magnetic action of a magnetic body, a stator core that is arranged around the outer periphery of the rotor body, and a bearing that rotatably supports the shaft of the rotor body. In a stepping motor comprising a front case and a rear case, at least one of the two cases is formed of a soft magnetic material such as an iron plate that is magnetized by the action of magnetism, and A stepping motor in which the rotor body and the one case are disposed close to each other, and an attractive force is created between the rotor and the one case by leakage magnetic flux from the rotor body.
