付構造。[Scope of Claim for Utility Model Registration] (1) A pressure introduction passage that is equipped with a sensor that detects combustion chamber pressure within the wall surface of the combustion chamber of an internal combustion engine, and that opens into the combustion chamber and introduces the pressure to the sensor pressure receiving section. 1. A pressure sensor mounting structure in which a diameter of the pressure introduction passage is made smaller than a diameter of the pressure sensor pressure receiving part at a specific portion in the passage. (2) The pressure sensor mounting structure according to claim 1, wherein the passage is configured in a tapered shape, and the specific portion is the narrowest end thereof. (3) The pressure sensor mounting structure according to claim 2, wherein the diameter of the tapered passage increases from the pressure sensor pressure receiving portion toward the combustion chamber.
