| 摘要 |
A mounting device for a pressure sensor is disclosed. The mounting device comprises a cylinder head having a threaded hole for mounting a spark plug, a sensor housing orifice penetrating into a combustion chamber and a sensor pressure receiving section in the sensor housing orifice. A pressure sensor is mounted in the sensor housing orifice. The pressure sensor comprises a housing inserted into the sensor housing orifice and having a pressure receiving section for directly receiving the combustion pressure, and a piezoelectric device housed in the housing and producing a voltage corresponding to the combustion pressure received at the pressure received section. The device comprises a presser member pressing the pressure sensor toward the pressure receiving section by tightening of the spark plug. A vibration absorbing member is interposed between the presser member and the pressure sensor so as to absorb the vibration and the displacement transmitted from the presser member.
