PROBLEM TO BE SOLVED: To provide a pressure reducing valve provided with a manual closure valve capable of saving space and reducing cost by integrating the pressure reducing valve with the manual closure mechanism. SOLUTION: An actuation member 81 is disposed on the back of a first pressure means through a spring member 82, and a manual operation part 86 and the actuation member are connected to each other to make it possible to advance and retreat the actuation member by rotation of the manual operation part 86. When the actuation member is advanced, the first pressure means M1 is forcedly advanced to apply a valve mechanism body to a valve seat for forming a valve closed state. COPYRIGHT: (C)2004,JPO
