電磁シユーブレーキ。 In an electromagnetic shoe brake that brakes the rotation of a rotating body by de-energizing the electromagnetic coil installed in the yoke and pressing the armature against the inner peripheral surface of a brake drum that is integrated with the rotating body using the elastic force of a braking spring. , the yoke is formed into a substantially rectangular shape with mutually opposing short sides and mutually opposing long sides, the electromagnetic coil is attached to an iron core formed on each short side, and the armature is approximately These armatures are interposed between the short side of the yoke and the inner peripheral surface of the brake drum by dividing the armature into two parts having a U-shape and loosely fitting them onto each short side of the yoke. The electromagnetic shoe brake is further characterized in that the braking spring is interposed between opposing short portions of the armature and provided along the long side of the yoke.
