Claims

[Scope of utility model registration request]

(1) At least one brake plate in which teeth formed on the inner circumferential surface mesh with teeth formed on the outer circumference of the rotating shaft, allowing rotation of the rotating shaft and the brake plate when energized. An electromagnetic brake device comprising an electromagnet and an elastic body that brakes the brake plate and rotating shaft via a pressing member when the electromagnet is deenergized, characterized in that the brake plate is formed with unbalanced structure.

(2) The electromagnetic brake device according to claim 1, wherein the unbalanced impact of the brake plate is formed by providing a hole formed in the mandrel.

(3) The electromagnetic brake device according to claim 1, wherein the teeth formed on the outer circumference of the rotating shaft are splines formed on the outer circumferential surface of the rotating shaft.

(4) The electromagnetic brake device according to claim 1, wherein the teeth formed on the outer periphery of the rotating shaft are teeth of a brake gear fitted to the rotating shaft.
