PROBLEM TO BE SOLVED: To provide a self-recording pressure measurement device easy to manufacture and assemble, and devised so that an error of a bourdon tube caused by dispersion in manufacturing can remarkably, simply and surely be adjusted. SOLUTION: The travel distance of a tube tip 13' of the bourdon tube 13 moved by variation of various kinds of fluid pressure such as water pressure and gas pressure is transmitted to a pen shaft 4 through a bendable span adjusting arm 11 capable of self-keeping the bent form and a nonlinear adjustment arm 12.
