Abstract:
Provided is a base unit for use in a disk drive apparatus and to be attached to a cover portion to define an enclosed space to be filled with a gas having a density lower than that of air. The base unit includes a base portion arranged to extend radially and support a motor capable of rotating about a central axis extending in a vertical direction; and a lateral wall portion arranged to extend axially upward from an edge portion of the base portion. The base portion includes a part accommodating portion defined by a through hole arranged to pass through the base portion in an axial direction, and arranged to accommodate at least a portion of a predetermined part; and a seal member arranged to close an end portion of the through hole on one axial side. The base portion and the lateral wall portion include a base made of a metal; a coating portion formed by electrocoating a surface of the base with at least a resin; and at least one exposed portion where the surface of the base is exposed. The at least one exposed portion is arranged in at least one of a predetermined first region and a second region. The first region lies on an axially upper end portion of the lateral wall portion, the axially upper end portion being opposite to the cover portion. The second region lies on an outer surface of the base portion, and is arranged to extend outward from an edge of the part accommodating portion so as to have a predetermined width.

Claim (Index 10):
A disk drive apparatus comprising:\n the base unit of  claim 1 , the base unit having an opening portion lying on an upper side of the base unit; a cover portion arranged to cover the opening portion of the base unit; a gasket held between an axially lower surface of the cover portion and an axially upper end surface of the lateral wall portion; a motor including a bearing mechanism arranged on the base portion, and a rotating portion supported through the bearing mechanism to be rotatable about the central axis; and an access portion arranged to perform at least one of reading and writing of information from or to a magnetic disk supported by the rotating portion; wherein the motor and the access portion are accommodated in the enclosed space; the cover portion includes a base made of a metal, a coating portion formed by electrocoating a surface of the base with at least a resin, and an exposed portion where the surface of the base is exposed; and the exposed portion of the cover portion is arranged to cover an area radially outside of a point of contact between the cover portion and the gasket in a region of the cover portion opposite to the upper end surface of the lateral wall portion.
