Abstract
A stepping motor includes a stator, a rotor which is rotatable to the stator, a rotor-side position regulation part which is fixed to the rotor and is rotated together with the rotor, and a stator-side position regulation part which is fixed to the stator. The rotor includes a rotary shaft, and a rotor magnet which is mounted on an outer periphery of the rotary shaft. The rotary shaft is integrally formed with the rotor magnet by resin. The stator-side position regulation part includes a first stator-side position regulation part which contacts the rotor-side position regulation part at a first position to regulate a rotation of the rotor in one direction, and a second stator-side position regulation part which contacts the rotor-side position regulation part at a second position different from the first position to regulate a rotation of the rotor in an opposite direction to the one direction.
