In the figure, 1 is a rotating shaft, 1a is a toothed part, 4 is a brake plate, 5a is a toothed part, 7 is a pressing member, 8 is a movable iron core,
8a is a through hole, 9 is a fixed core, 9a is a through hole, 10 is a spring receiver, 11 is a brake coil, 12 is a first elastic body,
13 is a second elastic body. Note that the same reference numerals in the figures indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

(1) At least one tooth portion formed on the inner circumferential surface meshes with a tooth portion formed on the outer circumferential portion of the rotating shaft through a predetermined back gap.
an electromagnet that allows rotation of the rotating shaft and the brake plate when energized; a first elastic body that brakes the rotating shaft and the brake plate via a pressing member when the electromagnet is deenergized; and one end of a second elastic body having a predetermined elastic force for preventing rocking between the respective tooth portions is passed through approximately the center of the movable core of the electromagnet to approximately the center of the suppressing member. An electromagnetic brake device characterized in that the second elastic body is placed in contact with one end surface of the elastic body and is disposed substantially parallel to the first elastic body.

(2) The electromagnetic brake device according to claim 1, wherein the second elastic body is formed of a compression coil spring.

(3) The electromagnetic brake device according to claim 1, wherein the other end of the second elastic body is in contact with approximately the center of the spring receiver.
