    摘要： An ultrasonic flaw detector (1) comprises a carriage (3) travelling on a guide rail (11), a guide arm (5) extending in a direction traversing the travel direction of the carriage (3) and supported by the carriage (3) so as to swing in a plane traversing the travel direction of the carriage (3). a probe holder (7) slidably supported by the arm (5), and a probe (9) mounted on said probe holder (7) so as to swing about two axes traversing each other. One of the axes is generally in parallel to the travel direction of the carriage (3). The carriage (3) is driven by a motor, and the probe (9) is moved by manual or motor-driving operation in a direction traversing the travel direction of the carriage (3) while pressing the probe (9) on a surface to be inspected, whereby the probe (9) follow the surface wall enough even if the surface is curved.
