An oil level gauge unit can prevent the leak of the oil and blow-by gas by dispersing and cutting off the fluid energy of the blow-by gas. A guide pipe(50) is installed from an outer side of a cylinder block(10) to the inside of an oil pan(30), and an oil level gauge(70) is inserted in the guide pipe. A mounting hole(11) having an inner diameter which is greater than the outer diameter of the guide pipe is formed on a side of the cylinder block corresponding to the inside the oil pan. One end of the guide pipe is connected to a connecting member(90) mounted on the top of the mounting hole and the other end is arranged through the mounting hole. One or more holes(51) communicated with a gap(13) between the outer circumference of the guide pipe and the inner circumference of the mounting hole are formed on the connection end of the guide pipe. |
