置。[Scope of Claim for Utility Model Registration] A hydraulic pump, a travel hydraulic motor driven by oil discharged from the hydraulic pump, a control valve that controls pressure oil from the hydraulic pump guided by the hydraulic motor, and a high-speed range. and a transmission that is capable of switching to a low speed range with a higher reduction ratio than the high speed range, and that reduces the rotation of the hydraulic motor in accordance with the reduction ratio and transmits the rotation to the wheels, and a transmission that switches the control valve to a neutral position. In a travel control device for a hydraulic vehicle, the hydraulic brake means is configured to apply a hydraulic brake to the hydraulic motor by squeezing return oil from the hydraulic motor. and applying a small hydraulic brake to the hydraulic motor when the transmission is switching to a low speed range and applying a larger hydraulic brake to the hydraulic motor when the transmission is switching to a high speed range. A travel control device for a hydraulically driven vehicle, comprising a control means for controlling the hydraulic brake means.
