Zusammenfassung:	A liquid-pressure driving system 1B for use in a working machine (see Fig.1) configured to supply an operating liquid to a liquid-pressure motor 17, the system comprising: a direction control valve 11 configured to switch a rotation direction of the motor; and a controller 2B configured to detect a rotation velocity 62 and a rotation direction 63 of the motor using a rotation velocity detector, and a posture of a structural body of the working machine 60,61 using a posture or gyro sensor 40. The controller is configured to control a flow rate upper limit 91 and flow direction of the operating liquid supplied to the motor based on signals output from the posture and rotation velocity detectors.
