を介設したリリーフ弁装置。A hole is drilled in the valve body that connects to the hydraulic booster and power steering device via the input passage and output passage, and to the hydraulic pump via the auxiliary passage, and the spool can be slid freely into the hole. A pressure chamber is formed at one end communicating with the auxiliary passage, and when the pressure in the pressure chamber exceeds a predetermined value, the spool resists the biasing force of a spring that biases the spool toward the pressure chamber. a first relief valve that moves and connects the auxiliary passage to a main passage that communicates the input passage and the output passage; and a first relief valve that is disposed between the input side liquid passage and the liquid tank of the power steering device; A relief valve device for a hydraulic pressure booster and a power steering device, comprising a second relief valve that connects the input side liquid path to a liquid tank when the pressure of the input side liquid path exceeds a predetermined value. A pressureless chamber connected to the liquid tank is formed at the other end of the spool in the hole, and a communication hole is bored in the spool to communicate the pressureless chamber with the main passage. A relief valve device in which the second relief valve is interposed.
