Power steering apparatus having hydraulic reaction mechanism

A power steering apparatus comprising:

• a main hydraulic path for supplying an oil pressure from a pump to a flow path switching valve connected to a power cylinder;
• a reactive oil pressure supply path branching from a portion of said main hydraulic path;
• and
• a hydraulic reaction mechanism for introducing part of the oil pressure, caused to diverge by said reactive oil pressure supply path, into a hydraulic reaction chamber for generating a steering reaction through a hydraulic reaction control valve mechanism comprising at least a first restrictor and a second restrictor and in which a path for a reaction force is provided from the portion between the path linking the first restrictor and the second restrictor to the hydraulic reaction chamber, the hydraulic reaction control valve mechanism being controlled in accordance with a traveling condition of a vehicle,
• wherein a restriction smaller in diameter than said main hydraulic path is arranged between a branch portion branching from said main hydraulic path and said hydraulic reaction control valve mechanism, midway along said reactive oil pressure supply path.
