けたことを特徴とするステツピングモータ。[Claims for Utility Model Registration] An end yoke and an intermediate yoke having comb-like salient poles that are inserted alternately along the inner surface of the body of the winding frame are fitted to a winding frame around which a winding wire is wound. Two sets of stators consisting of two sets of stators are placed in a motor frame with their back-to-back parts provided with intermediate yokes superimposed, and a rotor is arranged inside the two sets of stators and whose outer peripheral part is magnetized. In the stepping motor rotatably supported by the motor frame, the connecting hole and the connecting convex portion provided in the back-to-back portions of the two intermediate yokes are fitted into each other, and under this fitting, the connecting convex portion The diameter of the middle yokes is enlarged to connect the two intermediate yokes together, and a pair of large and small through holes that communicate with each other through this connection are provided in the back-to-back portions, and the flanges of the two winding frames covered by the back-to-back portions are provided. A locking pawl that is inserted into the small-diameter through hole and hooked on the edge of the hole is integrally provided on the portion, and the intermediate yoke and the winding frame are connected via the nail, and the winding frame is connected to the middle yoke through the pawl. A stepping motor characterized in that a terminal pin to which an end of a wire is connected and a printed wiring board outside the motor frame is attached to the flange portion.
