持したことを特徴とする圧力検出装置。In a pressure detection device for an internal combustion engine, a gasket and a ring-shaped pressure sensor are inserted into the mounting surface of an ignition plug that is screwed into a cylinder head, and the cylinder internal pressure is measured based on the output of the pressure sensor. A cylindrical guide member is fitted to the outer periphery of the pressure sensor, and positioning pieces protruding toward the inner periphery are arranged at approximately equal intervals on this guide member, and the gasket is placed concentrically with the pressure sensor via the positioning pieces. A pressure detection device characterized by holding.
