<p>PROBLEM TO BE SOLVED: To reduce the number of part items and also improve a freedom degree in the point of arrangement in a body, in a pressure reducing valve for gas opening a valve hole communicating with the pressure reducing chamber between a body and a diaphragm to a central part in a valve seat, and connecting a valve element able to be seated in the valve seat to a central part of the diaphragm, to be arranged coaxially to a valve shaft and fixed thereto. SOLUTION: In this pressure reducing valve 37 for gas, a bottomed mounting hole 97 opened to a side of a pressure reducing chamber 94 is provided in a body 34 coaxially to a valve shaft 107, a cylindrical valve seat member 98 formed with a valve chamber 103 storing a valve element 106 between itself and a blocking end of the mounting hole 97 to be inserted in the mounting hole 97 is fixed to the body 34, and a valve seat 105 facing in the valve chamber 103 is formed in an end part inner surface in a side of the pressure reducing chamber 94 of the valve seat member 98.</p> |
