Patent ID: 10293282

Abstract:
A mesh filter includes a filter unit connecting an outer peripheral surface of an inner cylinder and an inner peripheral surface of an outer cylinder. The inner cylinder, the outer cylinder, and the filter unit are integrally molded by injecting a thermoplastic resin into a cavity of a mold so as to have a one-piece construction. A portion of the filter unit other than a connecting portion between the inner cylinder and the outer cylinder has square-shaped openings formed by vertical ribs formed equidistantly so as to be orthogonal to an X-axis and parallel to a Y-axis, and lateral ribs formed equidistantly so as to be orthogonal to the vertical ribs and parallel with the X-axis. The vertical ribs and the lateral ribs have rib widths (L2, L3) in a range from 0.07 to 0.1 mm and thicknesses (L4, L5) along a center axis of the inner cylinder in a range from 0.2 to 0.4 mm.
