Claims

[Scope of utility model registration request]

(1) A field core 6' having a built-in electromagnetic coil 8 and having a plurality of protrusions 13, 13' projecting forward from the tip of the outer pole part 6'B, and a field core 6' that is fixed to a rotating member to be braked, and , a hub 2 arranged concentrically with the field core 6', a pressure receiving plate 7' arranged concentrically with the hub 2 and fixed to the tip of the convex portion 13, 13' of the field core 6', and the hub 2, a friction plate 3 integrally rotatable and movable in the axial direction, and an armature 5' that can freely perform magnetic attraction motion in the direction of the field core 6' using the convex portions 13 and 13' of the field core 6' as a guide. a compression coil spring 4 which gives the armature 5' the habit of pressing the friction plate 3 against the pressure receiving plate 7'; and a compression coil spring 4 fitted to the inner pole 6'A of the field core 6'; , a spring receiver 12 having an outward bent portion 12B facing the front surface of the field core and an inward bent portion 12C for receiving the compression coil spring 4.

(2) The negative actuation electromagnetic brake according to claim (1), in which the armature 5', field core 6', pressure receiving plate 7', and spring receiver 12 are press-molded steel plates.
