Abstract
A disk-shape resin molded article such as a gear comprises a rim, a boss, a web having a disk configuration for connecting the rim and the boss, and gear teeth formed on the rim. The molded article is produced by an injection-compression molding process which comprises injecting a molten resin into a cavity of a metal mold, and pressing a web site and at least one site selected from the group consisting of a boss site and a rim site in a thickness direction. The cavity may have a capacity larger than the solidified products by contraction amount of the injected molten resin.
