Claims

[Scope of utility model registration request]

A mounting block that is attached to the cylinder of an internal combustion engine is provided with a detection hole located inside the cylinder, and a piezoelectric element plate, a pressure transmission rod, and other attachments are housed inside the detection hole, and the detection hole The detection opening is sealed with a metal diaphragm, and each of the attachments is held under pressure between the inner surface of the detection hole and the diaphragm, so that a contact jaw surface is formed on the pressure transmission rod. A pressure sensor for an internal combustion engine, characterized in that the detection hole is formed with a locking surface that supports the jaw surface.
