PROBLEM TO BE SOLVED: To prevent the transmission delay of a brake force caused by variation in a plurality of brake members without slide.SOLUTION: A negative type electromagnetic brake device comprises: a brake shoe 8 disposed on a braked body so as to freely move back and forth; a movable element 5 movably disposed to be connected to the brake shoe; a stationary part 3 storing an electromagnetic coil 1 therein; and a plurality of brake members 2 installed in the stationary part for granting a restitutive force to the movable element. Elastic bodies 9Af and 9Bf are attached to two or more first concave portions formed on a first opposing surface of the stationary part with the movable element, and two or more second concave portions formed on a second opposing surface of the stationary part with the movable element, respectively; and with each elastic body, the projection amount from the edge face of the first concave portion or the second concave portion is set to be equal to or less than the movement displacement of the movable element.SELECTED DRAWING: Figure 1
【課題】摺動を行わずに、複数の制動部材のばらつきによる制動力の伝達遅れ防止。【解決手段】被制動体に対して進退自在に配置されたブレーキシュー8と、ブレーキシューに連結されて移動自在に配置された可動子5と、電磁コイル1を収納する固定子3と、固定子に装着されて復元力を可動子に付与する複数の制動部材2と、を備えたネガティブ型電磁ブレーキ装置であって、固定子のうち可動子との第1の対向面に形成された2以上の第1の凹部又は可動子のうち固定子との第2の対向面に形成された2以上の第2の凹部に、それぞれ弾性体9Af,9Bfが装着され、各弾性体は、第1の凹部又は第2の凹部の端面からの突出量が可動子の動作変位以下に設定されている。【選択図】図1
