STRUCTURE FOR PREVENTING OIL FROM TRICKLING DOWN

摘要

In order to prevent, when removing an oil filter from a cylinder block (2), oil from trickling down to an oil pan (4) mounted below the position at which the oil filter for the cylinder block (2) is mounted, a protrusion (22) which protrudes in a flange shape is provided integrally to the cylinder block (2) to a mounting mating surface (2a) thereof to which the flange (4A) of the oil pan (4) is joined, and a downward protrusion wall (23) for preventing the transfer of the oil is formed on the lower surface of the protrusion (22).
