ABSTRACT:
A power transmission member is provided with which it is possible to lessen the impact force produced when the head of a disk device hits part of a base member or the like. The power transmission member is a power transmission member of a mechanism for moving a head, used for recording on or reproducing from a disk, relative to a base member in a disk device, comprising a fixed component for attaching to a head, a power transmission component for receiving drive from a motor serving as a drive source, a linking component for linking the fixed component and the power transmission component, and a contacting component. The contacting component is fixed to the power transmission component, and comes into contact with part of the base member, or part of a member fixed to the base member, at least one end of the movement range of the head. The contacting component is also linked to the fixed component via the linking component in a state in which elastic deformation is possible only when an impact or the like creates an excessive force in the movement direction of the head.
