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. An engaging means that engages with the feed groove of the screw shaft to convert the rotational movement of the screw shaft into a linear movement of the carriage along the guide shaft, and for maintaining the engagement relationship between the engaging means and the feed groove. In the carriage transfer device, the engaging means is formed by an engaging protrusion integrally projecting from the leaf spring, and the engaging means is formed by bending the leaf spring, and the engaging protrusion is formed by bending the leaf spring. The leaf spring portion on the back side of the engaging protrusion is fixed to the carriage, and the spring piece is threaded through the spring piece and screwed into the carriage. A carriage transfer device characterized by being provided with an adjustment screw whose elastic force can be adjusted.
