Summary:PURPOSE: A gas pressure self-inspecting apparatus is provided to prevent the separation of the apparatus from an accumulator and a back head due to strong vibration and to prevent high-pressure gas leaking from the installation position of the apparatus. CONSTITUTION: A gas pressure self-inspecting apparatus comprises a body(21) which is installed in an accumulator and a back head of a hydraulic breaker or drilling machine, a piston(25) which is elastically installed and slid in the body, and a stopper(27) which is coupled to the body to prevent the separation of the piston from the body. The body, the piston, and the stopper are arranged on the same axis. One end of the piston is selectively protruded or retracted according to the pressure of high-pressure gas.
