力検出装置。 In a pressure detection device for an internal combustion engine, a ring-shaped pressure sensor is sandwiched between the mounting surface of an ignition plug that is screwed into a cylinder head, and the cylinder internal pressure is measured by the output of the pressure sensor. The part of the lead wire for taking out the output signal that is pulled out from a portion has a rigid structure from at least the root part to the part that protrudes a predetermined length from the upper end of the spark plug insertion hole of the cylinder head. A pressure detection device for an internal combustion engine, characterized in that a lead wire portion is supported through a side portion of a sealing member that is fitted into the upper end opening of the spark plug insertion hole.
