It moves, and the friction resistance difference between the upper surface and the lower surface causes the third
A force that rises in the direction of the arrow e in the figure acts, and a force that moves in the combined direction (arrow f) is received. However, the arrow d of the front conduit 1
Lateral movement in the direction is resisted by the side surface 2 ″ of the resistance plate 2 and is prevented from rising in the direction of the arrow e by the other side surface 2 so that the leading conduit 1 is eventually combined (arrow f). Direction) and the propulsion direction a is maintained in the direction of the center line c.
