PROBLEM TO BE SOLVED: To provide a container for water pressure gage and a water pressure gage that can accurately measure water pressure by evading fixation of periphyton.SOLUTION: A water pressure gage 1 comprises a water pressure detection part 2 which measures water pressure and a container 3 for water pressure gage in which the water pressure detection part 2 is built. The container 3 for water pressure gage has a water hole 35 for transmitting water pressure to the water pressure detection part 2 formed in a trunk part 33. An evasion part 36 is formed which has an opening part of the water hole at a position projecting from a peripheral surface 37. The evasion part 36 is formed into an annular projection part formed at the cylindrical trunk part so as to improve the strength of the evasion part 36, and the container 36 for water pressure gage can be easily manufactured by cutting a columnar member. |
