PURPOSE:To eliminate completely dust without mounting a breathing filter by composing a titled device of a filter filtering the dust included in air flow in a case and the 2nd filter filtering the air flowing out of a motor. CONSTITUTION:A filter box 16 is fixed to the motor at one shaft of the motor main body 15 fitted to a case outer wall 9 so as to cover the shaft and the motor and the external part are sealed sufficiently so as not to cause air leakage. Thus, the air in an enclosed case 2 in which a magnetic disk 2, a head slider 3, a carriage main body 4, and a circulating filter 8 are contained goes in and out all through a breathing hole 7 provided at a part of the outer wall 9 of the case via a filter 6, thereby preventing the intrusion of dust in the case and eliminating the need for the separate provision of a breathing filter. |
