Claims

[Scope of utility model registration request]

A brake lining loosely fitted and supported in the direction of the rotational axis, an armature that can be moved into and out of the front end of the brake lining and slidably supported in the direction of the rotational axis by a fixing bolt, and an armature on the opposite side of the armature from the brake lining. An electromagnetic brake consisting of a fixed iron core that is arranged facing each other with an axial gap and that is provided with an excitation coil and has a built-in brake spring, a brake plate that receives the pressing force of the brake spring via the brake lining and the armature, and the armature of the armature. An electromagnetic brake characterized in that a protrusion is provided on the peripheral edge facing the brake plate side that protrudes from the outer peripheral surface of the brake lining.
