摘要：
A sensor for detecting the combustion pressure of an engine, in which an upper fixing member and a casing are fixed while a pre-load is being applied to the upper fixing member, so that a pre-load may be applied to a piezoelectric element. Moreover, a tubular diaphragm for transforming a pressure into a strain and a pressure receiving face for receiving the combustion pressure are connected to each other through a plunger so that they may be kept away from each other.
