PURPOSE:To make the shaft centers of both stator assys coincide exactly with each other, by fitting engaging concave and convex sections to each other, and combining two stator assys provided with the sections, with each other. CONSTITUTION:A pulse motor is provided with a first stator assy 2 and a second stator assy 3 combined with each other, and with a rotor 4. The first and second stator assys 2, 3 are provided with a bearing for supporting the shaft 4a of the rotor 4 rotatably. So far as the first stator assay 2 and the second stator assy 3 are concerned, an engaging slot 17 is engaged with an engaging convex section, and ring-formed side walls are combined with each other, and in this state, peripheral walls 9 are spot-welded to each other.
