To provide a brake device capable of reducing a work load relating on operation of a preliminary brake in a case where a regular brake cannot be used.SOLUTION: A brake device 1 includes: a brake mechanism 2 for pushing a shoe 21 against a braked member of a railway vehicle, and braking the railway vehicle; a DC motor 43 different from a motor 33 for driving the brake mechanism 2; a battery 41 different from a vehicle power source 31 for supplying power to the DC motor 43; and a relay circuit 42 for controlling supply of power to the DC motor 43 from the battery 41, according to a preliminary brake command. The battery 41 supplies DC power, the DC motor 43 drives the brake mechanism 2 on the basis of the DC power, and the relay circuit 42 switches a route between the battery 41 and the DC motor 43 according to the preliminary brake command.SELECTED DRAWING: Figure 1 【課題】常用ブレーキが利用できない場合の予備ブレーキの作動に関する作業負担を軽減できる制動装置等を提供する。【解決手段】制動装置１は、鉄道車両の被制動部材にシュー２１を押し付けて鉄道車両を制動するブレーキ機構２と、ブレーキ機構２を駆動するモータ３３と異なる直流モータ４３と、直流モータ４３に電力を供給する車両電源３１と異なるバッテリ４１と、予備ブレーキ指令に応じて、バッテリ４１から直流モータ４３への電力の供給を制御するリレー回路４２と、を備える。バッテリ４１は直流電力を供給し、直流モータ４３は直流電力に基づいてブレーキ機構２を駆動し、リレー回路４２は予備ブレーキ指令に応じてバッテリ４１と直流モータ４３の間の経路を切り替える。【選択図】図１
