Claims

[Claims for Utility Model Registration] (1) An electromagnetic brake device that has an output shaft to which the motion of a rotating shaft is transmitted via a joint, and that applies braking force to the output shaft, a brake armature that is movably attached to the brake armature through a leaf spring and a boss and has a friction plate; an excitation coil that produces a magnetic flux that attracts the brake armature against the force of the leaf spring; and a magnetic path for the magnetic flux. and a brake plate formed integrally with the bracket and having an abutment surface that contacts the friction plate, and a hole communicating with the outside is provided in the abutment surface of the brake plate that faces the friction plate. An electromagnetic brake device characterized by: (2) In the electromagnetic brake device according to claim 1 of the utility model registration claim, the hole communicating with the outside contains grease containing lubricant for the friction plate, and the outside of the hole contains grease added to the inside of the hole. An electromagnetic brake device comprising a plug made of an elastic material such as rubber and having a corresponding surface convex outward.
