Claims

[Claims for Utility Model Registration] 1. A device in which a carriage on which a magnetic head is mounted swings around a predetermined axis, wherein the carriage is swingable around the predetermined axis, the carriage is provided at the distal end, and the carriage is swingable around the predetermined axis. a friction inner ring 1 fixed coaxially to the swinging center of a movable arm 8; at least three friction rollers 2 disposed inscribed in the inner peripheral surface of the friction inner ring; friction intermediate rollers 3 of the same number as the friction rollers 2, which are located at equal parts on a predetermined cylindrical surface and have a fixed axis parallel to the predetermined axis, and are rotatable around the fixed axis; a belt 4 which is wound around the outer peripheral surface of the friction intermediate roller 3 in a closed loop, and each portion between the adjacent friction intermediate rollers 3 is in surface contact with the outer peripheral surface of each of the friction rollers 2; 1. A magnetic disk device comprising: a motor 6 for commonly friction-driving; 2 Utility Model Registration In the device described in claim 1, the friction roller 2 consists of two concentric cylindrical parts, the outer peripheral surface of one of which is inscribed in the inner peripheral surface of the friction inner ring 1, and the outer peripheral surface of the other is in contact with the inner peripheral surface of the friction inner ring 1. A magnetic disk device characterized in that it is in circumscribed contact with a driving friction roller 5 fixed to the shaft of a motor 6.
