ABSTRACT:
This invention provides a hydraulic motor with a mechanical brake device in which a brake means is always pressed in position between the case body of the brake device and the brake operating member by the pressing force of plural spring members, and the brake operating member pressing the brake means is slid in the axial direction resisting against the spring members through cam means in response to a driving torque from a drive shaft of a hydraulic motor assembly so that the brake device always can be restrained from rotation of a free rotatable drive shaft during the non-operation of the hydraulic motor assembly and capable to be taken off restraint in response to a driving torque from the drive shaft of a hydraulic motor assembly.
