Summary:To provide an electromagnetic brake device capable of reducing generation of instantaneous braking force even when electric power supply to the electromagnetic brake device is shut off during traveling for any reason.SOLUTION: An electromagnetic brake device 16 includes: a brake stator; a rotating shaft; a brake disk; a brake armature 42; an adsorption mechanism for adsorbing the armature to the brake stator; a first energizing member for energizing the brake armature 42 in a direction separating from the brake stator; and regulation members for regulating rotation of the brake armature 42. Notches 63 to which the regulation members are inserted are provided in the brake armature 42. The notch includes a groove enabling displacement in the circumferential direction of the rotating shaft of the brake armature 42 relative to the regulation member. The electromagnetic brake device includes second energizing members each coupling the regulation member to the brake armature 42 and applying energizing force for hindering the displacement in the circumferential direction of the brake armature 42 to the brake armature 42.SELECTED DRAWING: Figure 4 【課題】走行中に何らかの理由で電磁ブレーキ装置への電力供給が遮断されても、瞬間的な制動力の発生を緩和できる電磁ブレーキ装置の提供にある。【解決手段】ブレーキステータと、回転軸と、ブレーキ板と、ブレーキアーマチュア42と、アーマチュアをブレーキステータへ吸着させる吸着機構と、ブレーキアーマチュア42をブレーキステータから離間させる方向へ付勢する第1付勢部材と、ブレーキアーマチュア42の回転を規制する規制部材と、を有し、ブレーキアーマチュア42は、規制部材が挿入される切り欠き63が設けられる電磁ブレーキ装置16において、切り欠きは、規制部材に対してブレーキアーマチュア42の回転軸の周方向へ変位を可能とする溝を有し、規制部材とブレーキアーマチュア42とを連結し、ブレーキアーマチュア42の周方向の変位を妨げる付勢力をブレーキアーマチュア42に付与する第2付勢部材を有した。【選択図】 図4
