Abstract

An electromagnetic coupling apparatus for interrupting power transmission is disclosed in which a terminal of a magnet coil for attracting an armature to a rotary body is connected with an electrical terminal of an electric connector directly outside of a fixing member without using a lead wire or the like therebetween. A stopper is secured in direct contact or with a small gap to a recess formed at part of the fixing member, thus preventing the rotation of the yoke including the magnet coil.
