Abstract
An electromagnetic coupling apparatus interposed between a fixed housing and a rotating member. The electromagnetic coupling apparatus includes a multiplate brake mechanism, a ringlike core member fixed in the housing, an annular exciting coil accommodated in an annular groove of the core member, and a ringlike armature member opposed to the annular groove of the core member. The armature member has an outer diameter larger than the outer diameter of the core member. The electromagnetic brake further includes a cylindrical pressure member having one end fixed to an outer circumferential portion of the armature member and the other end engaged with the multiplate brake mechanism. The cylindrical pressure member surrounds the core member so as to be movable in a direction of applying a pressure to the multiplate brake mechanism as being guided by the core member. The opposed portion between the core member and the armature member is formed by tapered end surfaces each having a predetermined tapered angle.
