PROBLEM TO BE SOLVED: To provide a disk drive configured to reduce a probability that particles enter the inside of the disk drive. SOLUTION: The disk drive includes: a hub for supporting a recording disk; a base member 4 which has a bearing hole centering on a rotary shaft of the hub; a bearing unit 12 which supports the hub so as to be freely rotatable with respect to the base member 4 and is at least partly fixed to the bearing hole 4h; and a sealing material 54 interposed between the bearing hole 4h and the bearing unit 12. A plurality of resin reservoirs 200 having fine recesses to store the sealing material 54 are arranged in a circumferential direction of a contact part , on at least one of an inner peripheral surface of the bearing hole 4h and an outer peripheral surface of the bearing unit 12 at the contact part thereof.
