PURPOSE:To make the sliding characteristic of a moving substance prominent and to enable a motor to withstand the external force of the moving substrance sufficiently which is produced through an output shaft, by providing a metal sliding axially between a stator and the moving substance. CONSTITUTION:A stator 1 of a linear pulse motor is composed cylindrically, on the inside diameter of which a pistonlike-shaped moving substance 2 is equipped. A metal 3 is equipped between the stator 1 and the moving substance 2. The metal 3 is constituted so as to slide along the inside diameter of the stator 1 and fixed to the outside circumference of the moving substance 2, together with which the metal 3 moves. The stator 1 is composed of iron cores with windings 4 wound over and laminated in the axial direction. The moving substance 2 is composed of permanent magnets 6 and iron cores 7 alternately laminated.
