A linear motion in which a screw shaft rotatably housed within the rotor core is screwed with a nut attached to the side plate of the stator so that it can be displaced in the axial direction as the rotor rotates. In the motor, nuts are attached to the side plates provided on both sides of the stator, and means for transmitting the rotation of the rotor to the screw shaft is provided at a predetermined position of the screw shaft rotatably housed in the rotor core. A linear motion motor characterized by being displaced in the axial direction while being screwed together with a screw shaft. 2. The linear motion according to claim 1, wherein the rotor rotation transmission means comprises a pin provided at a predetermined position on the screw shaft and a long groove bored along the center hole of the rotor core so as to engage with the pin. motor. 3. The linear motion motor according to claim 2, wherein the pin is attached to a connecting portion of a screw shaft.
