Abstract
To reduce weight and simplify mold structure, an annular metal fixture (1) embedded in a dust cover (2) has an annular base portion (3) and an inward peripheral tooth (4) integrally formed at the inner side thereof, the annular base part (3) is formed from one layer of flat plate and has a plurality of three-dimensional structures (6), which have projected portions (8) usable as a height position defining means when inserted into a mold for forming the dust cover, a plurality of notches (5) are circumferentially formed at the inner periphery of the inward peripheral tooth (4) in order to increase the diameter of the inward peripheral tooth (4) when fitted to the dust cover, and the three-dimensional structures (6) are formed at positions radially aligned with at least a part of the notches (5).
