[Scope of Claim for Utility Model Registration] 1. A lead screw provided on the outer periphery of a shaft that can slide in a hole provided in the rotor and a nut provided on the mounting plate of the stator yoke are screwed together as the rotor rotates. In the linear motor whose shaft is displaceable in the axial direction, a hole shaped like a non-cylindrical front shaft is provided between the end of the rotor collar and the bearing, and the front portion is inserted into the hole. A linear motor with a spacer inserted and fixed. 2. A linear motor characterized in that a pole that can be inserted into a gap formed by a non-cylindrical front shaft and a bearing is disposed on the outer periphery of the shaft. 3. The linear motor according to claim 2, comprising a pole in which half pieces disposed on the upper and lower surfaces of the non-cylindrical shaft are integrated with a spacer inserted into the front part of the shaft, or a spacer is glued to the half piece. .
