Abstract:
A sensor mounting structure for mounting, on a wall section of an intake pipe of an internal combustion engine of a motor vehicle a sensor for sensing a physical value of an interior of said intake pipe necessary for operating said motor vehicle, wherein said sensor is mounted by:providing in said wall section a sensor mounting hole of non-circular contour for inserting a part of said sensor into said intake pipe; forming in a housing a said sensor a first locking portion which allows said sensor to be inserted into said mounting hole in a specific orientation and engaged with an inner surface of said wall section, by turning said sensor through a specific angle after insertion; forming in said housing of said sensor a second locking portion for engaging with an outer surface of said wall section by inserting said sensor; holding said wall section of said intake pipe between said first and second locking portions; and setting said sensor so that a negative pressure of said intake pipe acts on said sensor, whereby said second locking portion is pressed against said outer surface of said wall section.
