Abstract
An electromagnetic clutch has an electromagnetic coil and a coil housing for accommodating the coil. The coil is inserted into the coil housing together with insulating members made of readily deformable insulating material. The insulating members are pressed downwardly by the coil and deformed according to an inner shape of the coil housing. As a result, the coil and the insulating members are accommodated in the coil housing with a preset gap between a surface of the coil and an inside surface of the coil housing, formed by the insulating members. The gap is filled with melted resin so that the coil is firmly secured in the coil housing. Thus, the coil can be readily secured in and insulated from the coil housing at a low cost.
