The present invention relates to a filtering apparatus for an oil press which enables filtration of oil to be stably performed in a short time by removing impurities deposited on an upper side of the filter. The filtering apparatus comprises: an inflow main body which is formed in the shape of a circular pipe to allow oil to be filtrated to flow through an upper portion thereof, has the filter installed on the inside, has a filtration container installed under the filter, has a discharge hole penetrating the outer circumferential side above the filter, and allows an impurity tray attached to the outer circumferential side thereof to encircle the outside of the discharge hole a rotation driving unit having an installation plate horizontally installed above the inflow main body, a motor installed on an upper side of the installation plate, and a rotation axis which is joined to the motor, penetrates the installation plate, and has a lower end portion located in the center of an upper side of the filter and a scraping unit which comprises a scraping blade which has one end portion, hinged to be able to be rotated on a lower end portion of the rotation axis, and the other end portion, close to the inner circumferential side of the inflow main body, bent to be convex toward the rotation direction, and formed to be inclined toward an inner circumferential side of the inflow main body, an installation step formed to protrude from the upper surface of the rear end of the scraping blade to the upside, a discharge rubber plate which is made of a synthetic rubber material having one end portion installed on the installation step, and the other end portion coming in close contact with the inner circumferential side of the inflow main body and is bent, a protrusion step formed to protrude from the upper surface of the front end portion of the scrapping blade to the upside, a spring installed between the protrusion step and the rotation axis to scrape impurities deposited on the
