Abstract
A magnetic disk drive device has a hub for driving a magnetic disk when the magnetic disk is placed on the hub. A drive magnet is fastened to the inner surface of the hub. A stator core, with a coil wound thereabout, is located in opposition to the drive magnet. A frame is provided for fixedly supporting the stator core. A cutout portion is formed in the bottom of the frame, and a flexible printed circuit is disposed within the cutout portion. The coil terminal wires of the stator core and flexible lead wires are connected to the flexible printed circuit. A plural number of protrusions integral with the frame are disposed within the cutout portion. An arc-shaped lead wire holder, which is arc-shaped along the circumference of the frame, is fitted to the plural number of protrusions.
