FIG. 3 is a diagram showing a cross section taken along the line in the direction of the arrow. FIG. 3 is a longitudinal sectional view of an embodiment of this invention. In the figure, 4 is a brake box, 5 and 7 are brake disks, 8 is a pressure plate, 9 is a nut, 10 is a movable core, 11 is an electromagnet, 13 is a mold wheel support member, 14 is a mold wheel, 15 is a screw member, 16 is a shaft, 19 is a pawl, 21 is a rotation control spring, 22 is a spring receiver, 24 is a brake spring, 26 is a pawl support member, and 28 is a pin. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

The inner circumference of the rotary shaft is fitted to the outer circumference of the movable rotating shaft so that the rotary shaft can freely move in the axial direction, and rotates integrally with the rotary shaft, and the vicinity of the outer circumferential edge on the negative side is attached to the fixed part. Opposing brake discs, a pressure plate whose negative side faces the other side of the brake disc and which is movable in the axial direction but cannot rotate; a screw member screwed into the inner circumference of the pressure plate; a negative side facing the pressure plate; a movable iron core facing the other side of the plate; a ring-shaped electromagnet disposed on the other side of the movable iron core that attracts and moves the movable iron core when energized;
A cylindrical claw support member disposed on the inner periphery of the electromagnet; a mold wheel rotatably disposed on the inner periphery of the electromagnet; a mold wheel rotatably supported on the claw support member; attracts and moves the movable iron core by a predetermined amount, and in response, a claw rotates the mold wheel by a predetermined amount, and when the electromagnet is deenergized, the pressure plate is moved by the brake via the movable iron core and the screw member. A brake spring that is brought into pressure contact with the other side of the disc, a rotating shaft that rotates together with the die wheel and whose end that passes through the movable iron core is integral with the screw member, and prevents axial movement of the pawl support member. means for controlling the mold wheel, a rotation control spring whose one end comes into contact with the mold wheel or a rotating part that rotates together with the mold wheel and controls the rotation of the mold wheel, and a bolt attached to the end of the electromagnet on the side opposite to the movable iron core side. In the case where the electromagnet has a spring holder that is fixed and receives the other end of the rotation control spring, an inner flange is provided on the inner periphery of the movable core side end of the electromagnet to prevent the pawl support member from falling off. An electromagnetic brake device characterized in that one end of the pawl support member is engaged with the spring receiver to prevent rotation.
