めの軸受機構。In a step motor in which a rotor is rotated forward and backward by pulse excitation of an excitation coil attached to a stator, and an output shaft is linearly reciprocated by screw connection with the rotor, one bearing for the rotor is attached to a body to which the stator is attached. and the mounting hole of one of the output shaft bearings are integrally formed, and the one bearing on the body side is integrally formed with the lid body which is fitted and attached to the stator mounting hole of the body body. A bearing mechanism for a step motor, characterized in that a mounting hole of the other bearing for the rotor and a mounting hole of the other shaft bearing for the output shaft, which face the mounting hole of the rotor, are integrally formed.
