PROBLEM TO BE SOLVED: To achieve a configuration of a pressure gauge that can be easily compactified and can suppress the manufacturing cost.SOLUTION: The pressure gauge of the present invention includes: a Bourdon tube 10; a base end side fixed member 11 connected and fixed to a base end of the Bourdon tube; an internal machine 20 connected to a tube tip 10d of the Bourdon tube; a support plate 14 for directly or indirectly supporting the base end side fixed member and internal machine; an external connection member 13 that includes a distribution channel 13g penetrating the support plate and has a rotor-like outer shape; and a communication pipe 12 that connects the base end side fixed member to the external connection member to communicate the inside of the Bourdon tube to the distribution channel. The external connection member integrally includes a connection section 13d that is disposed on one side of the support plate and connected to the communication pipe, a penetration section 13c engaging with the support plate, and a connection section 13a that is disposed on the other side of the support plate and connected to an external apparatus. The connection section is disposed between the internal machine and support plate. |
