<p>A metal fixture for a dust cover realizing reduction of the weights of parts and simplifying the mold structure of a dust cover mold. In the annular metal fixture (1) buried in the dust cover (2) to secure the dust cover (2) to its installation portion and comprising an annular base part (3) and inner diameter teeth (4) formed on the inner diameter side of the annular base part which are formed integrally with each other, the annular base part (3) is formed of one layer of flat plate and comprises a plurality of three-dimensional structures (6) partially on the circumference. The three-dimensional structure (6) comprises a projected part (8) usable as a height position restriction means when the metal fixture (1) is inserted into the dust cover mold. A plurality of cutout parts (5) for increasing the diameter of the inner diameter teeth (4) in fitting are circumferentially formed at the inner diameter edges of the inner diameter teeth (4). The three-dimensional structures (6) are formed at positions circumferentially aligned with at least a part of the cutout parts (5).</p> |
