PROBLEM TO BE SOLVED: To provide a fire extinguisher dispensing with a fitting member for fitting a Bourdon gauge and eliminating any necessity of forming a hole in a pressure resistant container for fitting the Bourdon gauge.SOLUTION: The fire extinguisher according to the present invention includes: a pressure resistant container 10 for storing a fire-extinguishing chemical; a seal plate 20 for sealing an opening 11 of the pressure resistant container 10; a Burdon gauge 30 for displaying a pressure inside the pressure resistant container 10; and a valve 40 having a needle part 41 for breaking the seal of the seal plate 20. The Burdon gauge 30 comprises a cylindrical leg part 31 forming a pressure introduction hole, a spiral part 32 continuously formed from the cylindrical leg part 31, a pointer 33 fitted at an end of the spiral part 32, and a scale plate 34 disposed parallel to the spiral part 32 to represent displacement of the pointer 33. The cylindrical leg part 31 is fitted to the seal plate 20.SELECTED DRAWING: Figure 1 |
