Abstract
An intake air amount detecting device for an internal combustion engine has a temperature detector housing disposed in an intake pipe of the engine and defining first and second air passages in which first and second temperature detecting elements are disposed, respectively. An electric heater is disposed in the first air passage upstream of the first temperature detecting element. Sleeves of a resilient shock-absorbing material are interposed between the temperature detector housing and the electric heater and the first temperature detecting element and between the housing and the second temperature detecting element, respectively, whereby the heater and the temperature detecting elements are protected from shock, vibration and oscillation produced during operation of the engine and automobile on which the engine is mounted.
