ーキ。[Claims for Utility Model Registration] 1. A fixed outer frame having a cylindrical shape with a bottom, a pair of support shafts erected vertically at the bottom of the fixed outer frame, and one circumferential end of which is pivoted to the support shafts. A brake drum includes a core made of a pair of substantially semicircular laminates arranged in a circular shape, and a cylindrical portion covering the outside of the pair of cores; It is equipped with a braking spring that presses against the inner peripheral surface of the cylindrical portion via a friction plate, and an excitation coil wound on the side opposite to the pivot in the circumferential direction of each of the cores. An electromagnetic drum brake characterized in that an air gap in the magnetic circuit of the excitation coil is formed between the excitation coil winding side end face of the excitation coil. 2. A release pin protruding outward from the bottom of the fixed outer frame is fixed to each of the cores, and a release knob having a pair of levers that engages with the release pin is pivoted to the bottom of the fixed outer frame. The electromagnetic drum brake according to claim 1, characterized in that the electromagnetic drum brake is equipped with a magnetic drum brake.
