ピーデイスク装置のリードスクリユ機構。[Claims for Utility Model Registration] A lead screw mechanism for a floppy disk device that converts the rotational motion of a lead screw rotated by a stepping motor into linear motion to move a carriage equipped with a magnetic head in the radial direction of a recording medium, a support member that supports the other end of the lead screw, one end of which is connected to the rotor of the stepping motor; and a support member that is attached to the stepping motor and presses the lead screw against the support member, and is capable of adjusting the pressing force. A lead screw mechanism for a floppy disk device, characterized in that it is equipped with a preload mechanism having an adjustment mechanism.
