Abstract: An improved structure of pressure gauge includes a bottom case, a pressure measurement assembly, a rotating assembly, a fulcrum piece, a coil spring, a scale meter, and an outer case. The pressure measurement assembly is installed above the bottom case and the surface thereof is shaped with concentric circular waves. The rotating assembly includes a sleeve body and a central rod. A fulcrum piece is installed across between the sleeve body and the central rod. A plurality of through holes and a coil retaining base are provided on the fulcrum piece. One end of the coil spring is screwed onto the coil slot and the other end thereof is installed on the coil retaining base. The outer case is located in the outer area of the bottom case and the fulcrum piece. A transparent cover body is installed on top of the outer case.
