レーキ装置。It is provided in the middle of a pair of supply and discharge passages that connect a fluid motor and a switching valve that controls the fluid motor, and when the fluid motor performs a pump action and discharges fluid to the supply and discharge passage on the discharge side. In a fluid brake device that applies a brake to a fluid motor by restricting the flow of fluid and increasing the internal pressure of a discharge side supply and discharge passage, a bypass passage in which an on-off valve is interposed in the middle of the supply and discharge passage. A pair of pilot passages are provided which are connected to the on-off valve and press the on-off valve to open when the internal pressure of each supply/discharge passage reaches a predetermined value, and When the fluid motor performs a motor action, the internal pressure of the supply-side supply/discharge path is guided to the on-off valve to counteract the pressure in the pilot passage, and the on-off valve is locked closed, while when the fluid motor performs a pump action, the on-off valve is guided to the on-off valve. A fluid brake device characterized by having a control passage that guides tank pressure to open an on-off valve.
