ガスリーク防止構造。 A housing that is inserted into the exhaust pipe has a protective tube with a hole at the base end, and a sensor element whose base end is closed and the tip is open to the atmosphere is housed in an outer cylinder whose base end is tightly connected to the housing. In an exhaust gas leak prevention structure for an O 2 sensor in which a peripheral portion of the housing is supported by a support member in the outer cylinder, the inner peripheral surface of the base end of the housing is formed into a tapered surface whose diameter decreases toward the base end, and the sensor A flange having a tapered surface corresponding to the tapered surface of the housing is formed on the base end side of the element, a ring gasket is interposed between each of the opposing tapered surfaces, and an end surface of the flange on the opposite tapered surface side and An exhaust gas leak prevention structure for an O 2 sensor, characterized in that a spring for pressing the ring gasket is compressed between supporting members in the outer cylinder.
