グセンサー。 On the outer periphery of the inner housing, which is a cylindrical member,
A sensor main body having output characteristics according to the knocking level of the internal combustion engine is attached, and the outer periphery thereof is covered with an outer housing having a connector portion on the upper side of the side for taking out the electric signal generated in the sensor main body to the outside, and the above-mentioned In a knocking sensor that is attached to the internal combustion engine body by bringing one end surface of the inner housing into contact with the outer wall of the internal combustion engine body using a fastening member that penetrates the hollow part of the inner housing, the part that touches the sensor body is made of a soft material. A notsking sensor is characterized in that it has a double-layered outer housing whose outer side is made of a harder material than the material that touches the sensor body.
