するパワーステアリング装置。 A hydraulic oil circuit that includes an oil pump driven by the engine and a power cylinder connected to the steering transmission device of the vehicle, and supplies hydraulic oil pressurized by the oil pump to the power cylinder while being controlled by a control valve. In the power steering system, which boosts the steering force through this power cylinder, a cooling water circuit that circulates engine cooling water to a heater core for heating and a heater fan that blows air through this heater core are installed. A heat exchanger that exchanges heat with the hydraulic oil circulating in the hydraulic oil circuit is interposed in the cooling water circuit, and a bypass passage that bypasses the heat exchanger is provided, and the bypass passage and A power steering device comprising: a valve for switching the heat exchanger; and a control means for opening the bypass passage via the valve in conjunction with the operation of the heater fan.
