Actuator supporting apparatus of hard disk drive

An actuator supporting apparatus of a hard disk drive which includes a housing having a base and a cover, the apparatus comprising:

• a pivot bearing including an inner ring, an outer ring, and a rolling member, which are installed coaxially, to support an actuator arm of the actuator supporting apparatus to pivot;
• a support structure having a first coupling member coupled to the base to support the inner ring accommodated by the base, and a second coupling member coupled to the first coupling member to fix the cover to the first coupling member;
• and
• a buffer member interposed between a flange portion of the first coupling member and the inner ring to buffer vibrations and impacts.
