Abstract
A steering apparatus for an industrial vehicle includes: a manual steering circuit which includes a first valve opened/closed according to an operation of a steering wheel and supplies hydraulic oil discharged from a hydraulic pump to a steering cylinder through the first valve; an automatic steering circuit which includes a second valve opened/closed according to a calculation result of automatic operation control and supplies the hydraulic oil discharged from the hydraulic pump to the steering cylinder through the second valve; and a branching valve which is disposed between the hydraulic pump and the first and second valves and branches the hydraulic oil to the manual steering circuit and the automatic steering circuit. The branching valve is a priority valve which preferentially supplies the hydraulic oil to the manual steering circuit at a designed flow rate equal to or larger than a predetermined flow rate for operating the steering cylinder.
