ABSTRACT:
An object of the present invention is to almost completely prevent relative rotation between a pressure gauge and valve main bodies. A gear D is fixed to a pressure gauge guide connected to the pressure gauge. A gear A having the same axis as the gear D is fixed to the valve bodies. A support shaft is rotatably inserted into an insertion hole at a non-center position of a bottom portion of a pressure adjustment guide. Gears C, B fixed to both ends of the support shaft are engaged with the gears D, A. The pressure gauge does not rotate relative to the valve main bodies when a handle is rotated.
