Patent ID: 7472578

Claim:
A gas sensor comprising: an element holder body including a housing, available to be mounted on a gas flow passage for gas to be measured, and an insulation member fixedly supported in the housing; a sensor element, fixedly supported in the insulation member, which has a base end whose opposing surfaces are formed with a plurality of electrode terminals, respectively; an atmosphere-side insulator covering the base end of the sensor element and internally incorporating a plurality of spring terminals held in contact with the electrode terminals, respectively; and a tilting device disposed between the atmosphere-side insulator and the element holder body and including at least one convexed portion formed on at least one of the atmosphere-side insulator and the element holder, the convexed portion having an apex portion in abutting contact with a surface of the other one of the atmosphere-side insulator and the element holder such that the atmosphere-side insulator rests on the element holder so as to be tiltable relative to an axis of the element holder at freely variable angles to be inclined depending on a degree of inclination of the sensor element.
