Further, it is very difficult to make the density of the oil filter assembly even, and to filter oil uniformly throughout the sectional area of the oil filter assembly due to uneven pressure of the oil passing through the oil filter assembly, thereby deteriorating the efficiency of the filtration and the characteristics of the oil filter assembly and shortening the longevity of the oil filter assembly 10 and the oil.

Further, it is required to insert the cover-fastening rod 13 into the inner space of the inner tube of the oil filter assembly 10 and moreover at the center of the inner tube for easy fastening due to the long inner space of the inner tube when the cover-fastening rod 13 is inserted into the housing 51 for fastening the cover and assembling of the housing assembly.
