Abstract
A fluid filtering apparatus for a vehicle, which comprises: a filter element (2) provided with an element body (20) having a tubular shape and with a sealing member (21, 21) having a plate-shape, which is joined to each of opposite ends of the element body (20); a filter case (1) for receiving the filter element (2); and a pair of holding members (3, 4) coming into close contact with the sealing member (21) of the filter element (2) in an axial direction of the filter element (2) so as to divide an inside of the filter case (1) into a dirty-side zone (C1) and a clean-side zone (C2), between which the filter element (2) is placed. The sealing member (21) is joined to the element body (20) by ultrasonic fusion, which is applied exclusively to an outer peripheral portion (210) of the sealing member (21).
