Claims

[Scope of utility model registration request]

A yoke to which electromagnetic coils wound around excitation cores formed at a plurality of locations in the circumferential direction are fitted and fixed; a plurality of armatures supported by the yoke via leaf springs; An electromagnetic shoe brake comprising a brake drum having a cylindrical portion fitted into a yoke, and a braking spring that presses the armature against the brake drum, wherein the braking spring is made of a thin plate spring material, and the braking spring and the braking spring are made of a thin plate spring material. Leaf springs are arranged in parallel on the magnetic pole surface side of the yoke via excitation iron cores, and their base ends are fixed to the magnetic pole surface side of the yoke, and the free end portions of the leaf springs are fixed to the armature to apply the braking. An electromagnetic shoe brake characterized in that a central portion of a spring is pressed against the armature.
