From the pressure adjusting port 28, the vacuum pressure operating device 2
Since the negative pressure fluid supplied to 6 is introduced into the vacuum chamber 58 through the first passage 56, the vacuum pressure in the vacuum chamber 58 is set to be substantially the same as the pressure adjusting port 28. In this case, under the action of the negative pressure fluid introduced into the vacuum chamber 58, the diaphragm 52 and the pair of disk members 66 and 67 are given a force for pulling back upward integrally, and the diaphragm 52 and the pair of disk members 66 and 67 are applied. When the force for pulling the disk members 66 and 67 upward upward and the spring force of the second spring member 50 are balanced, the valve body 36 is seated on the seat portion 42 to be in a valve-closed state, and is preset by the handle 76. The desired vacuum pressure is applied to the vacuum operating device 2 through the pressure adjusting port 28.

That is, the work of setting the vacuum pressure can be easily performed by incorporating the pressure gauge into the cylindrical handle. In this case, even if the handle and the pressure adjusting nut are rotated integrally, the pressure gauge itself does not rotate,
Since the scale position of the pressure gauge does not move, the numerical value indicated by the pressure gauge can be easily read.
