Abstract
A stator housing of an electromagnetic clutch has a receiving portion for receiving an exciting coil and a bottom with through holes. The through holes are formed by pressing so as to have a tapered portion, a cross-sectional area of which becomes large toward the opposite side of the exciting coil. The exciting coil is received in the receiving portion so as to face the through holes and fixed by a molded resin which is filled into a space between the exciting coil and the receiving portion as well as the through holes. Accordingly, a fixing structure for preventing the exciting coil and the mold resin from coming out of the stator housing can be provided with low cost and high productivity.
