Claims

[Scope of utility model registration request]

A field core and a pressure-receiving plate fixed to the equipment casing side at a predetermined distance from each other; a rotating shaft pivotally supported on the equipment side with its tip facing the inner hole of the field core and the pressure-receiving plate; an armature disposed between the field core and the pressure plate so as to be movable in the axial direction; and an outer peripheral portion between the armature and the inner braking member of the pressure plate, the inner hole portion of which is fixed to a hub integral with the rotating shaft. In a negative actuation type electromagnetic brake equipped with a disc-shaped disc facing the
A flange is formed on the hub, and screw members that can be freely adjusted forward and backward relative to the plane of the disk are screwed into a plurality of screw holes provided in the flange, and a screw member that can be freely adjusted forward and backward with respect to the plane of the disk is inserted into a portion of the disk that faces the screw member, A negative actuation type electromagnetic brake characterized in that a flexible portion is formed that is bent by the pressure of the screw member and moves the braking member facing portion of the outer periphery in parallel.
