COVER FOR EXHAUST GAS SENSOR

摘要

A cover for an exhaust gas sensor, according to an embodiment of the present invention, comprises: a cover body which is extended in a direction to surround an exhaust gas sensor; a coupling part which fixes the cover body to one side of an exhaust pipe; an inlet part which sends the exhaust gas into the cover body; an outlet part which discharges the exhaust gas to the outside of the cover body; and a foreign material cutoff part which protects the exhaust gas sensor from the foreign materials flowing from the outside. Thus, the present invention cuts off foreign materials flowing from the outside by the foreign material cutoff part by preventing the inlet and outlet parts from disturbing the flow of the exhaust gas, thereby securing the operation reliability of the exhaust gas sensor.
