Claims

[Scope of utility model registration request]

An ultrasonic probe that rotates around a tubular or round rod-shaped test material that is transported straight without rotating, a cylindrical body into which the ultrasonic probe is inserted, and a part of the cylindrical body. a lock portion provided, a ring provided at both ends of the cylindrical body and inscribed in the outer periphery of the test material, a cover for fixing the ring to the cylindrical body, and the test material and the cylindrical body. an ultrasonic medium surrounded by the ring, an inlet for feeding the ultrasonic medium, a cylindrical screw having a male screw on the cylindrical outer periphery for attaching the ultrasonic probe, and the cylindrical tube. a small bevel gear that has a female thread that meshes with the male thread of the screw and rotates around the axis of the cylindrical screw; and a small bevel gear that meshes with the small bevel gear and is orthogonal to the small bevel gear. A large bevel gear that rotates as a rotating shaft, and a bearing fixed to the cylindrical body to support the small bevel gear, restrain rotation of the cylindrical screw, and enable the cylindrical screw to move in the axial direction. An inspection device characterized by:
