Patent ID: 7426869

Claim:
A mounting structure for a pressure sensor of an internal combustion engine in which said pressure sensor having a case that receives a pressure detection part and a pressure introduction pipe that protrudes from said case to the outside is mounted on a mounting member that has a mounting hole, with said pressure introduction pipe being inserted into said mounting hole, said structure comprising: an elastic snap fit portion that is formed on said mounting member so as to protrude from a surface thereof, said snap fit portion having an engagement protrusion formed at an end thereof so as to protrude to a side opposite to said case; and an engaged portion that is formed on said case so as to be engaged with said engagement protrusion; wherein said case comprises an outer member and an inner member; wherein said snap fit portion is forced to flexibly deform to said pressure sensor when said pressure sensor is attached to and detached from said mounting member; and wherein the flexible deformation of said snap fit portion is limited by abutment of said engagement protrusion against said outer member and said inner member.
