Abstract
A turntable for a storage disk drive apparatus includes a plate member made of a ferromagnetic material and a central resin member arranged at the center of the plate member and provided with an outer peripheral portion positioned above the plate member. The central resin member includes claws extending downwards from the outer peripheral portion and claw position holes overlapping with the claws in the direction parallel to the center axis of the central resin member. The claw position holes include inner surfaces spaced apart from an edge of the plate member. The inner surfaces are defined by the resin. The central resin member includes a resin layer extending in the direction perpendicular to the center axis. The resin layer exists between the portion of the edge of the plate member around the claw position holes and the claw position holes.
