ABSTRACT:
An improved structure of a gas sensor is provided which is designed for achieving desired crimping of an end portion of a sensor housing to establish a higher degree of gas-tight seal between the housing and a sensor element. The sensor element is fitted within the sensor housing. The end portion of the sensor housing is crimped or bent to urge the sensor element into constant abutment with an inner wall of the housing through a sealing member. The housing has an unique shape and dimensions selected to ensure the higher degree of gas-tight seal regardless of the degree of wear of a crimper and/or dimensional error of the housing.
