拡径掘削機のローリング修正機構。 A hollow traction shaft that can be connected to the outer pipe for traction is attached to one end of the cutter chamber, and a fixed shaft for connecting the towed tube is supported to the other end by bearings that restrain movement in the axial direction. A rotary shaft connectable to a rotary drive inner tube that can move in the direction is inserted into the traction shaft, and a coupling ring for transmitting rotary driving force can be slid in the axial direction on the protrusion inside the cutter chamber of the rotary shaft. 1. A rolling correction mechanism for a diameter-expanding excavator, characterized in that the rotary shaft is fitted with a clutch plate at the inner end of the cutter chamber.
