Abstract
A stepping motor is provided which is capable of increasing output torque and transmitting power to a power transmission portion precisely. In a stepping motor including: a rotor having a magnetized rotor magnet and a power transmission portion and rotating around a rotation axis; and a stator formed of a coil for generating a magnetic field by electric energy supplied thereto, and a yoke constituting a magnetic path for the magnetic field, the rotor magnet transmits power to the power transmission portion through a connection hole, and the connection hole has a rotation stopping shape as seen in a plane perpendicular to the rotation axis such that distances from the rotation axis to outer circumferential points are not constant.
