Abstract
An improved structure of a gas sensor made up of a sensor element and a first and a second hollow cylindrical porcelain insulators covering the sensor element. The first porcelain insulator is laid on the second porcelain insulator in alignment within a body of the gas sensor. A positioning mechanism is provided which works to establish and keep alignment of the first and second porcelain insulators, thereby avoiding undesirable inclination of the first and second porcelain insulators which may cause damage to the sensor element.
