Abstract:
1. A pressure gauge comprising: a pressure gauge body capable of visually confirming a pressure indication of pressure to be measured; a tubular pressure introduction port projected from the pressure gauge; a tubular pressure introduction section having recessed grooves formed in a circumferential direction of the tubular pressure introduction section to introduce the pressure to be measured into inside the pressure gauge, sliding members, which are arranged to fit into the grooves in a state where the pressure introduction section is inserted in the tubular pressure introduction port, wherein the sliding members slide over an inner surface of the pressure introduction port to make the pressure introduction section rotatable with respect to the pressure gauge body, a restricting member provided on the pressure introduction section, and a ridge provided in the pressure gauge body, which locks the restricting member in an engaged manner to restrict rotation of the tubular pressure introduction section with respect to the pressure gauge body.
