Abstract
The air-fuel-ratio sensor has a mounting body, a cup-shaped protector enclosing a sensitive element, and gas passage holes and deflectors are provided on the protector wall in such a manner that a gas stream outside the sensor generates swirl of the gas in the cup-shaped protector, the amount of the swirling gas increasing with the distance from the mounting body.
