Claims

[Claims for Utility Model Registration] A fixed cylinder, a disk rotatably disposed coaxially with the fixed cylinder, a rotary cylinder supported on the upper part of the disk and disposed facing the fixed cylinder, and a lower surface of the rotary cylinder. A magnetic head supported on the outer periphery, a stator-side rotary transformer fixed inside the fixed cylinder, and a rotor-side rotary transformer supported at the lower part of the disk and disposed opposite to the stator-side rotary transformer with a space therebetween. and a motor for rotating the rotary cylinder, wherein the motor includes an annular vibrating body disposed on the outer circumferential side of the rotary transformer on the stator side, and a vibrating body disposed on the outer circumferential side of the rotary transformer on the rotor side. The ultrasonic motor comprises an annular rotating body provided therein, and the vibrating body and the rotating body are respectively fixed inside the fixed cylinder and below the disk so that they are arranged with appropriate abutting force against each other. A rotating cylinder device characterized by:
