Abstract
To provide a disk drive capable of being prevented from rattling due to vibrations by a motor or eccentricity of a disk, support arms formed at both sides of a U-shaped traverse holder of a traverse unit have ribs protruding therefrom. Shaft portions protrude outward from front ends of the arms while bearing portions are provided on sidewalls of a chassis. The bearing portion has an axial hole formed in the side wall and a flexibly deformable, resilient arm extending forward spaced from the sidewall by a given distance, the axial hole having a front portion and a rear portion, the front portion being smaller in height than the rear portion, and the height of the front portion of the axial hole being slightly larger than outside diameter of the shaft portions. The shaft portions are fitted in the axial holes. The ribs are squeezed within the resilient arms.
