Abstract
An anti-corrosion structure of a gas sensor is provided. The gas sensor includes a hollow cylindrical air cover assembly made up of an inner and an outer cover. The air cover assembly has formed therein air inlets through which air is admitted into the gas sensor. The inner and outer covers are joined together through at least one crimped portion which defines a water drain path extending from the air inlets to outside the air cover assembly, thereby draining the water entering at the air inlets out of the gas sensor. This avoids accumulation of the water between the inner and outer covers to minimize gap corrosion therebetween.
