Claim 11:
12. A disk device comprising:
a magnetic disk having a recording surface;
a magnetic head configured to read and write information from and to the magnetic disk:
a suspension holding the magnetic head and configured to move between a load position where the magnetic head is located on the recording surface and an unload position where the magnetic head is apart from the recording surface;
a ramp including an attachment tab with a through hole, configured to hold the suspension at the unload position;
a housing that accommodates the magnetic disk, the magnetic head, the suspension, and the ramp, the housing having a support surface with a screw hole to support the attachment tab; and
a screw including
a screw head,
a screw shaft extending from the screw head in a first direction and fitted into the screw hole through the through hole, and
a first contact surface located on the screw head or in-between the screw head and the attachment tab, tapering in the first direction, and contacting the attachment tab, the screw holding the attachment tab in-between the support surface and the first contact surface, wherein

the housing includes a side surface connected to an edge of the support surface and facing the attachment tab,
the attachment tab is spaced apart from the side surface, and
in a direction orthogonal to the first direction, a shortest distance between the edge of the support surface and a major diameter of a female thread on the screw hole is equal to or less than a distance between a major diameter of a male thread on the screw shaft and a diameter of the screw head.
