Abstract

PURPOSE:To prevent grease from scattering from a bearing, by providing an inclined hole for generating an air flow which increases pressure as a hub is rotated at a high speed, between the hub to which a magnetic disk has been installed, and a housing. CONSTITUTION:An inclined hole 14 provided between a housing 4 in which labyrinth packing 11 has been formed, and a hub 7 is made to communicate with an air suction port 15 made on a holding member 10 of a magnetic disk storage device. As the hub 7 which has been pressed into a spindle 11 held by bearings 2, 3 is rotated at a high speed, an air flow 16 going downward is generated, and pressure in the inclined hole 14 rises remarkably. The grease of the upper bearing 2, which is leaking from the labyrinth packing 11 is pressed into by this pressure, scatters in the direction of a magnetic disk 8, and it is not stained.
