A pair of grooves 3, 3! are formed on both sides 7, 7' of the quadrilateral shading coil 6 corresponding to the center of the square shading coil 6. The shading coil 6 is moved toward the one end side 10 side by sliding against the grooves 3 and 3', and the central part of the one end side 10 is bent inward to close the side surface of the laminated core 1. By coming into contact with the enlarged width section 8,w, the upper surface of the enlarged width section 8,w is engaged with the locking pieces 4,'', the upper surface of the enlarged width section 9,q is engaged with the engagement pieces 5, 5', and the shading coil 6 is engaged with the engagement pieces 5,5'. The both sides T and 7' are locked by the locking pieces 4, 4', 5, and 5' so that they do not come out of the pair of grooves 3 and 3'. A pair of grooves 3, 3' are formed in the magnetic pole face 2 of the laminated iron core 1, which is formed by overlapping and fixing laminated iron plates, and locking pieces 4, 4' are provided at the opening edge of one end of the grooves 3, 3'. A locking piece 5, 5' is provided protrudingly on the opening edge of the other end of the groove 3, and the center part and one end of both sides 7, 7' of the quadrilateral shaded coil 6 are provided. Enlarged J width parts 8, 8', 9, 9' are formed, enlarged width parts 8, 81 correspond to the central parts of the grooves 3, 3', both sides 7, T' are loosely formed in the grooves 3, 3'. The shading coil 6 is moved toward the one end side 10 of the grooves 3 and 3', and the central part of the one end side 10 is bent inward to abut against the side surface of the laminated core 1 and enlarged. Since the upper surfaces of the width portions 8, 8', 9, and g are locked to the locking pieces 4, 4', 5, and 5', the upper surfaces of the enlarged width portions are locked to the locking pieces. The shading coil is reliably prevented from coming off from the pair of grooves, and there is no need to weld the shading coil to the laminated core, which has the effect of simplifying the installation of the shading coil.
