PROBLEM TO BE SOLVED: To provide a gauge handle type pressure reducing valve in which the relative rotation of a pressure meter and a valve main body is almost completely eliminated. SOLUTION: A gear D is fixed to a pressure meter guide 66 connected to a pressure meter 64, and a gear A whose shaft is the same as that of the gear D is fixed to valve main bodies 10 and 11. A supporting shaft 69 is inserted into a through hole 68 at the non-central position of a bottom part 60B of a pressure adjusting guide 60 so as to be freely rotated, and the gear C and the gear B fixed to both the edge parts of the supporting shaft 69 are respectively engaged with the gear D and the gear A. Then, when a handle 59 is rotated, the pressure meter 64 is prevented from rotating relatively to the valve main bodies 10 and 11. COPYRIGHT: (C)2005,JPO&NCIPI
