To miniaturize a brake device for a railway vehicle.SOLUTION: A brake device 1 for a railway vehicle has a power point input with power and an action point for generating braking force to a braked member W. The brake device includes a brake lever 4 in which the power point side generates first displacement and second displacement in this order when generating the braking force and a magnification modulation part 6 for making the magnification of the displacement on the action point side with respect to the first displacement on the power point side be larger than the magnification of the displacement on the action point side with respect to the second displacement on the power point side.SELECTED DRAWING: Figure 1

    【課題】鉄道車両用ブレーキ装置の小型化を図る。【解決手段】鉄道車両用ブレーキ装置1は、力が入力される力点および被制動部材Wに制動力を生じさせる作用点を有し、制動力を生じさせる際に力点側が第1変位と第2変位とをこの順に起こすブレーキ梃子4と、力点側の第1変位に対する作用点側の変位の倍率を、力点側の第2変位に対する作用点側の変位の倍率よりも大きくする倍率変調部6と、を備える。【選択図】図1
