Abstract: A slope of an HDD door comes in contact with a slope formed on a lower wall. At this time, when screws of the HDD door are fastened, a fastening force is generated at the HDD door in a direction parallel to the plane direction of the PC housing. The HDD united with the HDD door moves slightly in a parallel direction in proportion to the fastening degree of the screws. At this time, the slope slides to go up on the slope, so the HDD moves slightly upward. When the screws are fastened fully up to the allowable torque, the HDD is firmly attached to the upper wall.
