Helix traveling carriage and helix traveling washing machine

A contrast vertically extending cylindrical wall center strut helical wall wound becomes helical structure of the conservation process efficiently performed as can be helical traveling carriage and the screw traveling cleaning such as cleaning to provide a machine. An in spiral motion washer 20 of the present invention, the direction of the force down the spiral wall 13 by its own weight by the engagement of the rotational coupling portion 54 and the strut 12, it is converted into a moment of the strut 12 around, thereby while swirling around the strut 12 can descend on spiral wall 13, the cleaning device 80 is transported smoothly becomes possible to clean efficiently helical structure 10. .FIELD 1
