PROBLEM TO BE SOLVED: To enable a connector part to be connected and disconnected with a connecting means smoothly and securely and prevent damage from being inflicted to the connecting means at the time of such connection/disconnection by providing a rotation regulating member with an elastic member which fixes an anchorage ring mounted on the connector part of an ultrasonic probe, in a freely detachable manner, to the connecting means so that the member can move into the axial line direction of the probe. SOLUTION: A retaining cylinder 53 is provided by screwing it into a connecting cylinder 52 insetted in a connecting adapter 50, and a pinching ring 70 is screwed into the retaining cylinder 53. In addition, a stopper ring 71 made up of an elastic ring with a circular cross section is sandwiched between the retaining cylinder 53 and the pinching ring 70. Further, the connector part of an ultrasonic probe 11 is fitted into the stopper ring 71 and the rotor 26 of the probe 11 is connected to the connecting adapter 50 to screw the retaining cylinder 53 into the connecting cylinder 52. In addition, the pinching ring 70 is screwed into the retaining cylinder 53 to clamp the ring 70 by a required torsional amount and thereby, the inner diameter of the stopper ring 71 is shrunk to bring the ring 71 into contact under pressure with a fixed ring 25. Thus, it is possible to prevent the fixed ring 25 from rotating together with the rotor 26. |
