１記載の回転スキヤナの回動機構。[Claims for Utility Model Registration] 1. A non-rotatable frame, a rotating body rotatably supported by the frame, and a rotating body held opposite to the inner peripheral surface of a cylindrical subject. In a rotary scanner that scans the inner circumferential surface of a subject by rotating the rotating body, one of a pin or a guide groove is attached to the rotating body so as to be rotatable integrally with the rotating body. the other of the pin or the guide groove is formed in the frame, the end of the pin is fitted into the guide groove, and the guide groove is a spiral or helical groove with an angular range of 360° or more; A rotating mechanism for a rotary scanner, characterized in that the angular range of the guide groove is a range in which the rotating body and the probe can rotate. 2. The rotating mechanism for a rotary scanner according to claim 1, further comprising a stopper provided near the circumferential edge of the guide groove so as to be able to arbitrarily change the position of the circumferential edge of the guide groove.
