<p>This invention is to provide a motor structure highly durable with a simple structure and usable within a wide temperature range, and provided with sliding parts such as a screw structure for transferring a driving force and a rotation preventing mechanism for an output shaft. In a motor structure having an output shaft with a screw screwed to a screw part provided on the center of a rotor rotated by electromagnetic interaction to move the output shaft in the axial direction by the rotation of the rotor, either one of sliding contact parts is formed of PPS resin, the other is formed of metal, and a nitride layer is formed on its surface. The sliding contact parts include the screwed part between the center of the rotor and the output shaft, and another sliding contact parts include the output shaft and a through-hole part for the output shaft provided on a stator housing. <IMAGE></p> |
