To reduce a manufacturing cost of a parking brake device for railway vehicle.SOLUTION: A parking brake device 100 for railway vehicle comprises a brake 10 that generates parking brake force when pressed against a wheel 2, and an actuator 20 that compressed air is supplied, contracts to separate the brake 10 from the wheel 2, and when the compressed air is discharged, extends to press the brake 10 against the wheel 2. The actuator 20 is arranged on a radially outer side of the wheel 2 along the radial direction of the wheel 2. The brake 10 is arranged between the actuator 20 and a tread surface 2b of the wheel 2, and is pushed against the tread surface 2b of the wheel 2 with extension of the actuator 20.SELECTED DRAWING: Figure 1

    【課題】鉄道車両用パーキングブレーキ装置の製造コストを低減する。【解決手段】鉄道車両用パーキングブレーキ装置100は、車輪2に押し付けられることによってパーキングブレーキ力を生じる制輪子10と、圧縮空気が供給されると収縮して制輪子10を車輪2から離間させ、圧縮空気が排出されると伸長して制輪子10を車輪2に押し付けるアクチュエータ20と、を備え、アクチュエータ20は、車輪2の径方向に沿って車輪2の径方向外側に配置され、制輪子10は、アクチュエータ20と車輪2の踏面2bとの間に配置され、アクチュエータ20が伸長することにより車輪2の踏面2bに押し付けられる。【選択図】図1
