ことを特徴とする円板ブレーキ装置。 A rotating disk fitted into the rotating shaft so as to be movable in the axial direction, a disk-shaped movable iron core provided so as to be movable only in the axial direction facing one side of the rotating disk, and the rotating disk via the movable iron core. A disc brake device comprising: a brake spring that performs a braking action by pressing the movable core against a fixed part facing another side surface; and a fixed core that attracts the movable core against the brake spring when an electromagnetic coil is excited. , When the gap between the fixed core and the movable core in the braking state increases due to wear of the braking surface and reaches the allowable suction limit value, the contact piece that contacts the outer peripheral side surface of the movable core on the braking surface side is moved to the fixed part or the fixed part. A disc brake device characterized by being provided with an alarm means which is electrically insulated and attached to either one of the iron cores, and which generates electrical conduction through contact between the contact piece and the movable iron core to issue an alarm.
