A pilot-operated check valve is disposed between the hydraulic motor and the high pressure selection valve and is oriented so as to prevent liquid from being discharged from the hydraulic motor; 1. A braking device for a hydraulic motor, comprising: pilot means for transmitting pressure to the pilot operation check valve provided in a supply/discharge path on the low pressure side. (2) The braking device for a hydraulic motor according to claim 1, wherein the pilot operated check valve has a check valve slow return mechanism.
