(57) Abstract :
The invention provides a mounting structure for an oil level gauge that can avoid the damaging of a seal section of the level gauge
insertion hole. The level gauge insertion hole (15) includes an introduction section (41), a seal section (42) and a reduced diameter
section (45) in that order from an outer open end thereof. The seal section consists of a smooth hole having a constant inner
diameter D2 which is greater than the outer diameter (Di) of the insertion portion (34) and small than the outer diameter DO of an
O-ring (25) which is fitted around the insertion portion. The inner peripheral surface of the seal section (42) is located outside of a
tapered conical plane (St) defined by connecting an outer open end (41a) of the introduction section (41) and an inner edge (43a)
of the reduced diameter section (43).
