PROBLEM TO BE SOLVED: To provide a brake device that is hardly influenced by a temperature condition and can stabilize buffering performance.SOLUTION: A brake system 9 includes: an amateur 13 having a brake pad 17; a core 12 in which a coil 16 for generating electromagnetic force to attract the amateur 13 is disposed; and a brake spring 15 for applying a force in a direction of pulling the amateur 13 away from the core 12. A counterbore hole 12a is provided on a surface of the core 12 facing the amateur 13. A resin 18 that expands when a temperature raises is provided in the counterbore hole 12a, and buffer rubber 19 is provided between the resin 18 in the counterbore hole 12a and the amateur 13. The buffer rubber 19 is protruded from a magnetic pole face of the core 12 by a predetermined dimension.SELECTED DRAWING: Figure 3

    【課題】 温度条件による影響を受け難く、緩衝性能を安定させることができるブレーキ装置を提供する。【解決手段】 ブレーキパッド17を備えたアマチュア13と、前記アマチュア13を吸引する電磁力を発生させるコイル16が内部に配置されたコア12と、前記コア12から前記アマチュア13を引き離す方向に力を付与する制動ばね15とを備えたブレーキ装置9において、前記コア12の前記アマチュア13との対向する面に座ぐり穴12aを設け、前記座ぐり穴12aの内部に温度が上昇すると膨張する樹脂18と、前記座ぐり穴12a内部の前記樹脂18と前記アマチュア13の間に緩衝ゴム19とを設け、前記緩衝ゴム19は、前記コア12の磁極面より所定寸法突出させた。【選択図】 図3
