摘要：
A power steering apparatus includes a main hydraulic path, a reactive oil pressure supply path, and a hydraulic reaction mechanism. The main hydraulic path supplies an oil pressure from a pump to a flow path switching valve connected to a power cylinder. The reactive oil pressure supply path branches from a portion of the main hydraulic path. The hydraulic reaction mechanism introduces part of the oil pressure, caused to diverge by the reactive oil pressure supply path, into a hydraulic reaction chamber for generating a steering reaction through a hydraulic reaction control valve mechanism controlled in accordance with the traveling conditions of a vehicle. A restriction smaller in diameter than the main hydraulic path is arranged between a branch portion branching from the main hydraulic path and the hydraulic reaction control valve mechanism, midway along the reactive oil pressure supply path.
