Claims

[Scope of utility model registration request]

Oil comprising a filter paper for filtering contaminated oil, a central cylinder supporting the filter paper by upper and lower end plates, and a relief valve provided in the central cylinder to drain contaminated oil from a side channel when the filter paper becomes clogged. In the filter, attach the relief valve support to the middle 6 cylinders.
An oil filter characterized in that the center cylinder and the relief valve are integrated by integrally forming the central cylinder and providing a relief valve between the support body and the end plate.
