PROBLEM TO BE SOLVED: To provide a pressure gauge with a large damping effect and a simple structure.SOLUTION: A pressure gauge includes: a display board 4 located on a front-face side of a cylindrical casing 3 with a bottom; a Bourdon tube 5 located inside the casing 3; a mounting board 61 provided in the vicinity of a tabular portion 31 of the casing 3; and a displacement transfer mechanism 6 located between the mounting board 61 and the display board 4 and having a rotary shaft 64 to be rotated thereby in accordance with displacement of the Bourdon tube 5, where the rotary shaft 64 is rotatably supported by a bearing unit 8 on an end plate 62. The bearing unit 8 comprises a housing portion 81 for housing a viscous resistance agent O that is kept in contact with a periphery of a shaft portion 641 of the rotary shaft 64 to damp rotation of the rotary shaft 64, and a cap portion 82 for preventing leakage of the viscous resistance agent, the cap 82 being located between the end plate 62 and the display board 4. |
