Gas sensor having improved structure for installation of protective cover
 An improved structure of a gas sensor is provided. The gas sensor includes a gas sensitive element, a holder retaining therein the gas sensitive element, and a protective cover installed on the holder. The protective cover has a flange which is retained in a groove formed in the holder by crimping an outer extension formed on the holder adjacent the groove. The geometries of the groove in the holder and the flange of the protective cover are so determined as to provide for ease of installation of the protective cover on the holder, firm engagement of the protective cover with the groove of the holder, and ease of machining of the groove of the holder.
