Abstract
To provide a stepping motor which can precisely and reliably detect stopping of a rotor with respect to a stopper with a simple structure, i.e., positioning of a base point of the rotor, and provide a motorized valve using it. The stepping motor includes a statorand a rotorrotationally driven by the stator, and a detection rotordetecting a rotation position of the rotor. The detection rotoris rotatably disposed on a co-axial center L with the rotorand rotationally driven via a rotation drive mechanism between the rotorand the detection rotor. The rotation drive mechanism has a drive play having a predetermined length or angle in the rotation direction.
