Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the flying-away of grease in a misted state from a bearing part, with respect to a head actuator of a magnetic disk drive. SOLUTION: In the head actuator 5 of a magnetic disk drive which is supported rotatably around a shaft 2 through the bearing part 1 to seek a magnetic head slider 4 at a prescribed position on a magnetic disk 3 rotating at high speed, the bearing part 1 has a pair of bearings fixed to the shaft 2 by making the edge of a labyrinth seal 8 face oppositely, wherein an open end of one gap between inner and outer wheels 6 and 7 is closed by the labyrinth seal 8, and a magnetic seal part 11 which is disposed between the bearings 9 and uses magnetic fluid 10.
