PRESSURE DETECTOR

PURPOSE:To obtain the detector with high reliability for high pressure by surely fixing a sensing body to a housing in contact. CONSTITUTION:A step part 22 is provided to the outer periphery of the insertion end part of the sensing body and a closed end side is reduced in diameter; and the step part 22 is fitted in a stopper part 11 projecting from the inner periphery of the housing 1 and the outer periphery of the sensing body 2 is fixed to the inner periphery of the housing 1 in contact. Consequently, even if high pressure is applied from a pressure lead-in part, the sensing body 2 never shifts. Further, even if the connection part between the sensing body 2 and the housing is damaged owing to excessive pressure, the sensing body 2 is prevented from coming out, so the sealing performance and safety for pressurized fluid are improved greatly and the high-reliability detector for high pressure is obtained.
