Abstract: A glow plug with combustion pressure sensor is disclosed having a cover and a housing with which a piezoelectric element is hermetically accommodated. A lead wire having flexibility is employed to supply electric power to a heating member. The lead wire, fixedly connected to the heating member, extends through an insertion bore of the cover and is hermetically bonded to an inner circumferential wall of the insertion bore. When the heating member is axially displaced upon receipt of a combustion pressure, the lead wire flexes to absorb the resulting displacement, causing a joint portion between the cover and the lead wire to have no drag against the displacement. This allows the piezoelectric element to detect the combustion pressure with high precision.

Abstract: A gas sensor is disclosed including a gas-concentration detecting element, a casing accommodating the gas-concentration detecting element, a lead wire delivering a detected voltage potential to an outside, an insulator holding the lead wire in electrical relationship with respect to the housing, a columnar elastic sealing member, air holes formed in the casing for admitting atmospheric air to an inside thereof, and a water repellent filter. The water repellent filter, formed in a cylindrical shape, is disposed between the casing and the insulator, and a cylindrical elastic member is disposed in at least one of an area between the water repellent filter and the casing and another area between the water repellent filter and the insulator. With the casing caulked, the water repellent filter and the cylindrical elastic member are fixed in place.
