Abstract: PURPOSE: An adjusting device of a swash plate type hydraulic piston motor for a driving unit of an excavator is provided to stably and accurately maintain or change the tilt angle of a swash plate in a hydraulic piston motor by employing a mechanical stopper. CONSTITUTION: An adjusting device of a swash plate type hydraulic piston motor for a driving unit of an excavator comprises a swash plate(20), a speed change assembly(40), and a mechanical stopper(50). The swash plate is embedded in a housing(10) of a hydraulic piston motor, with one side at a tilt angle and one lower side at a set angle(θ). The speed change assembly applies pressure to the opposite upper side of the swash plate in order to change the tilt angle within the set angle range, thereby changing the low or high speed of the hydraulic piston motor into high or low speed. The mechanical stopper supports the swash plate at the controlled tilt angle regardless of whether the pressure applied by the hydraulic piston of the hydraulic piston motor is parallel to the pressure applied by the speed change assembly and controls the speed of the hydraulic piston motor to the desired speed.
