Claims

[Claims for Utility Model Registration] In an electromagnetic clutch/brake driven by a leaf spring whose one end is fixed to a hub and the other end is fixed to an armature; A sliding ring 35 has a predetermined gripping force on the inner diameter of the bushing and is press-fitted so that its rear end on the side opposite to the armature protrudes by a predetermined amount.
and; an intermediate shaft portion is slidably inserted into the inner hole of the sliding ring, the front end in the axial direction has means for fixing the armature and the leaf spring, and the rear end has means for fixing the armature and the leaf spring. a drive pin 36 having a flange portion having an outer diameter larger than the inner diameter; and an axial gap between the sliding ring and the flange portion is a gap between the armature and the friction plate of the rotor field when the armature is released. An automatic gap adjustment device for an electromagnetic clutch/brake, characterized in that the gap is set equal to .
