In a hydraulic driving device for a cargo handling vehicle, a power running torque limit value setting unit sets a power running torque limit value to a minimum rotation speed set in advance, in a case where a determination unit determines that operations of second hydraulic cylinders including a lowering operation of a first operating portion are simultaneously performed, a rotation speed command value setting unit sets a rotation speed command value to a maximum value from between a lowering required rotation speed based on an operation amount of the first operating portion and a second hydraulic cylinder required rotation speed based on operation amounts of the second operating portions, and the power running torque limit value setting unit sets the power running torque limit value to the second hydraulic cylinder required rotation speed based on the operation amounts of the second operating portions, and a control unit controls an electric motor to rotate at a rotation speed based on the rotation speed command value and controls the electric motor to rotate at a rotation speed based on the power running torque limit value in a case where an output torque of the electric motor shifts toward a power running side.
