PURPOSE:To provide a driving mechanism for a weld section inspection machine capable of accurately detecting the correct synchronization drive and travel distance of wheels and capable of smoothly lifting the inspection machine by quickly lowering its whole height. CONSTITUTION:Wheels 19 of inlet pipe side self-propelled wheels 7 and wheels 19 of guard pipe side self-propelled wheels 2 are separately driven and turned by driving motors and direction changing motors provided respectively. When the when frame and wheel 19 of one inlet pipe side self-propelled wheel 7 are changed in direction, the movement is transferred to a distance recorder 8 via a gear device, and the distance recorder 8 is turned by the same angle. At the time of an abnormality, a composite cable 9 is strongly pulled, the composite cable 9 is removed from a stopper, the movement of the composite cable 9 is transferred to a spring type pressing mechanism 4 via a wire to tilt it, an inlet pipe side frame 3 is lowered along a linear guide 5 by its tare weight, the total height of an inspection machine is quickly lowered, and the weld section inspection machine is smoothly lifted.
