摘要： A turntable for storage disk drive apparatuses includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and formed by injection-molding a resin. The central resin member includes a disk guide portion provided on an upper surface thereof to guide a central hole of a disk and a plurality of gate recess portions indented upwards from a lower surface of the central resin member. The gate recess portions include ceiling surfaces positioned higher than the plate member. The ceiling surfaces include a plurality of gate cut portions formed in an injection molding process.
