Correction 1984. 3.12 The scope of claims for utility model registration shall be amended as follows. Utility Model Registration Claims (1) A hydraulic drive device in which one rotating shaft of a hydraulic differential motor is connected to the wheel side via a differential gear, and the other rotating shaft is connected to the disc brake side. (2) The hydraulic drive device according to claim 1, wherein the rotating shaft is an output shaft. (3) The hydraulic drive device according to claim 1, wherein the rotating shaft is a drive shaft. (4) The hydraulic drive device according to claim 1, wherein the hydraulic differential motor is a plunger motor. (5) The hydraulic drive device according to claim 1, wherein the hydraulic differential motor is a vane motor. (6) The hydraulic drive system according to claim 1, in which the disc brake is driven and operated via a clutch pedal. (7) The hydraulic drive system according to claim 6, wherein a solenoid switching valve is interposed between the disc brake and the clutch pedal. (8) The hydraulic drive system according to claim 6 of the utility model registration claim, in which a pressure reducing valve is interposed between the disc brake and the clutch pedal. The brief description of the drawing has been amended as follows. "It is a front view" on page 10, line 15 of the specification is corrected to "Front view, FIG. 3 is a circuit diagram of a hydraulic drive device according to another embodiment of the present invention."
