    Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic device which reduces wear and damage to a seal member by an opening on a cylinder, and a brake pressure control device using the same. SOLUTION: A port 514 communicating with the outside of a reservoir device 5 is opened on the inner peripheral surface 511a of a cylinder hole 511 in the reservoir device 5. A hollow part 515 is formed in a reservoir body 51 concentrically with the ports 514. An annular thin piece 516 is formed between the inner peripheral surface 511a of the cylinder hole 511 and the hollow part 515 so as to surround the port 514 in a radial direction, and is radially pressed outward with the port 514 as a center in a range narrower than an inside diameter of the hollow part 515, thereby being flexibly deformed outward. As a result, a root portion of the thin piece 516 has a curved surface in the inner peripheral surface 511a of the cylinder hole 511 while the opening 514a of the port 514 is recessed outward from the inner peripheral surface 511a of the cylinder hole 511.

    Abstract: PROBLEM TO BE SOLVED: To provide a structure that is simple, and exerts no resistance to fluid flow at movement of a valve body, in a valve used for a reservoir tank of a hydraulic brake system for vehicle.SOLUTION: A reservoir chamber valve 1 of a hydraulic control type includes a closing member 13 that seals a valve seat 26 of a valve element 22, and is subjected to an initial stress via a first compression spring 14; and a tappet 12 that is coupled with a reservoir piston 10 urged by a second compression spring 15, and extrudes the closing member 13 from the valve seat 26, when an inherent power ratio is generated between a spring initial stress and a force acting in hydraulic manner. The first compression spring 14 and the closing member 13 are guided in a filter 24. The valve element 22 including the valve seat 26 and a filter 24 including a guide means are fabricated as an integrated plastic member 20.
