ABSTRACT:
An improved structure of a gas sensor is provided. The gas sensor includes a hollow housing in which a gas sensing element is disposed, a protective cover installed on an end of the housing, a metallic cover installed on the other end of the housing, and an insulator in which end portions of leads connecting with the gas sensing element are disposed. The insulator is retained at a flange thereof in the housing elastically using a washer. The protective cover is welded at an end thereof to the whole circumference of the end of the housing.
