Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power steering device suitable for a large-sized hybrid vehicle having a driving mode which permits driving even with the rotation of an engine stopped, and to provide a steering device for the hybrid vehicle, which is effective even under a condition where oil pressure to be supplied to the power steering device cannot be obtained with the rotation of the engine stopped. SOLUTION: This steering device comprises an auxiliary power steering device 25 with an electric assist motor provided for a steering shaft in line with the hydraulically-operated power steering device 20. The electric power steering device 25 is controlled so as to be automatically operated if no oil pressure is supplied. COPYRIGHT: (C)2004,JPO
