() The arrow A and the lower position of the lower end of the rod 81 are The d-shaped member 83 of the "]" shape penetrates the link member 8 in the horizontal direction. The link member 83 is coupled to the rod body. It is also expected that the side view is L-shaped in the open space, and the right side of the plane of the 2 series is::=82 and the: the central part of the font frame 髀M ± A and the L-shaped plate 82a is provided. The L-shaped plate 82a is supported by the shaft portion 85 of the support Λ #; the portion 85 is rotated. Further rod-μ ★ τ is changed to WT in the wheel structure... The protrusion _a = = is placed in contact, and I b6a is the cylindrical portion of the drum 80 of the slave shaft. The direction is therefore: by the upper and lower position adjustment lever 8" the arrow s of the main figure 4: after the movement, the flat plate 82b of the hub 82 will raise the roller to move upward. At this time, since the drum "rotates" and comes into contact with the flat plate 82b, the upper and lower position adjusting lever 81 can be reduced, and the rotatory body can be prevented from being worn, and good operability can be ensured. In order to contact to protrude: the lower portion is the cylindrical portion of the drum 86 of the rotating shaft, so that the projection (four) 66a is caused by the rotation of the upper adjusting rod 81 toward the right side of the body (the direction of the arrow S in Fig. 4) 13 1343781 Moving upward 66, the upward movement of the protruding portion 66a causes the end portion of the opposite side of the joint portion of the first link member 76 and the beam member 66 to also rotate upward with the cymbal member 06 as the center. The upward combustion of the rod member 76 causes the central grading roller 27b to pass through the second link member 77 and the spring 。. After the central grading roller 27b is moved upward, the first side tidying wheel 27a and the second side grading roller 27aI At the same time, it is moved upward by the center grounding roller 70b and the first side drive shaft 7A.
