Claims

[Scope of utility model registration request]

A carriage equipped with a head device, a guide shaft that guides the carriage in the radial direction of the information recording disk, and a screw shaft that has a spiral feed groove formed on its outer circumferential surface and is rotationally driven by a rotational drive means. A carriage transfer device comprising a follower pin that engages with the feed groove of the screw shaft to convert the rotational movement of the screw shaft into linear movement of the carriage along the guide shaft, and a presser plate that holds the follower pin between the carriage. 2. The carriage transfer device according to claim 1, wherein the presser plate extends to a contact portion between the screw shaft and the follower pin.
