Abstract
A ultrasonic flaw detector driving apparatus including a driving apparatus which is equipped with an arm mounted respective side faces of a main frame of the ultrasonic flaw detector driving apparatus so as to allow the arms to move into an open and closed position. A resilient member provides a force which acts on the respective arms in such a direction so as to urge the arms into the open position. A ratchet prevents the arms from being opened by the resilient member as teeth engage with a pawl in a stepwise manner. Rollers are rotatably mounted to a tip of the respective arms and are in rolling contact with the guide rail on which the driving apparatus travels. The arms are moved to the open for mounting the driving apparatus to the guide rail and thereafter the arms are moved to the closed position. Thus, the main frame of the driving apparatus can be position movably fixed onto the guide rail.
