Abstract
A liquid is made to flow into a filter case from a tangential direction at any point on a side surface of the filter case and produces a swirling flow. Bubbles collected in a center of the swirling flow are retained by a retainer plate, thereby removing the bubbles from the liquid. A filter element filters the liquid from which the bubbles were removed.
