ABSTRACT:
A device for shifting a carriage on which the magnetic head of a disk drive is carried, the disk drive being used with magnetic disks. A mating element mounted to the carriage is in resilient contact with a helical groove formed on a threaded shaft. A retaining member having a retaining portion is mounted on the carriage. The retaining portion is usually not in contact with the wall defining the helical groove, but bears against the wall when the shaft stops abruptly or a strong external force is applied, for example. Thus, the mating element is prevented from disengaging from the groove.
