PROBLEM TO BE SOLVED: To provide a linear stepping motor capable of ensuring the stroke of a shaft as large as possible, even in a structure where the size of the motor is cut down in the axial direction.SOLUTION: A linear stepping motor includes a rotor 150 held on the inside of stator assemblies 130, 140 in a rotatable state. The rotor 150 includes a screw nut 154 at a position offset to the front side, and the screw nut 154 is screwed over the male screw structure of a shaft 170. The rotor 150 is manufactured by injection molding a raw material of resin, with rotor magnets 152, 153 and the screw nut 154 as an insert material. |
