置のキヤリツジ組立て構造。[Scope of Claim for Utility Model Registration] In a magnetic disk device in which a drive shaft is inserted and fixed by shrink fit or press fit into a cylindrical carriage to which a magnetic head arm is attached, and the material has a coefficient of thermal expansion larger on the carriage side than the drive shaft. , with respect to both ends 5a and 5b of the drive shaft 5 in the cylindrical hole of the carriage 8, an intermediate portion 5c between the two ends,
The diameter is relatively small, and the diameter difference between both end portions 5a, 5b and the intermediate small diameter portion 5c is such that a portion 8c of the cylindrical portion of the carriage 8 corresponding to the drive shaft intermediate portion 5c is closer to the center of the drive shaft. A carriage assembly structure for a magnetic disk device, characterized by having minute dimensions that act as a stopper to prevent bending.
