Claims

[Scope of utility model registration request]

(1) A field core 6' containing an electromagnetic coil 8 and having an outward bent portion 6'C at its front end, and a plurality of protrusions fixed to the bent portion 6'C of the field core 6'. 1
3.13', a pressure receiving plate 7' provided with a pressure receiving plate 7', a /'% bar 2 arranged concentrically with the field core 6' and the pressure receiving plate 7' and fixed to the braked rotating member, and the protruding portion 1.
3. An armature 5' that can freely perform magnetic attraction movement in the direction of the field core 6' using 13' as a guide; The friction plate 3 faces between the armature 6' and the armature 5', and the friction plate 3 is connected to the pressure receiving plate 7.
The compression coil that provides sliding properties to press the field core 6' includes the spring 4, the outward bent portion 12B that fits into the inner pole 6'A of the field core 6' and faces the front surface of the field core, and the compression coil spring 4. A negative actuation type electromagnetic brake comprising a spring receiver 12 having an inwardly bent portion 12C for receiving the spring.

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