Claims

[Scope of utility model registration request]

A cup-shaped case, a cover plate fixed to cover the opening of the case, an oil outlet hole that also serves as a cylindrical mounting hole formed in the center of the cover plate, and an oil outlet hole of the cover plate. A plurality of oil inlet holes are formed around the outlet hole, and the oil inlet holes are formed in a thick cylindrical shape and are built concentrically in the case, and the outer circumferential side communicates with the oil inlet hole, and the inner circumferential side communicates with the oil inlet hole. a filter element communicating with the outlet hole; an inlet-side check valve formed by applying an elastic valve piece to the inner surface of the oil inlet hole;
an outlet side check valve installed near the oil outlet hole in the inner cylinder portion of the filter element;
This outlet side check valve includes a valve housing consisting of a valve plate and a spring receiving plate each having an oil passage hole and defining an inner cylindrical portion of the filter element, and a valve housing fitted to the oil passage hole of the valve plate. 1. An oil filter comprising: a valve body; and a spring mounted between the valve body and the spring receiving plate to bias the valve body in a valve-closing direction.
