Will do.

  In other words, as shown in FIG. 4, when the first eccentric shaft 6 rotates and reaches the top dead center, the scaffold guiding unit 100 of the present invention has the adjustment shaft 40, the stopper 50, and the nut 70. One side of the scaffold 10 is raised while moving up and down along the long hole 31 of the underlay member 30 and the guide hole 11 of the scaffold 10.

Next, while the first eccentric shaft 6 rotates and reaches the bottom dead center, the adjusting shaft 40, the stopper 50, and the nut 70 are lowered while the protruding piece 63 of the second buffer member 61 is first moved. When the pressure is applied, the lower end of the stopper 50 pushes down the locking step 32 of the underlay member 30 and lowers the scaffold 10.
As described above, when the adjustment shaft 40, the stopper 50 and the nut 70 are moved up and down, the adjustment shaft 40, the stopper 50 and the nut 70 do not come into contact with the scaffold 10, so that no impact, noise, wear, etc. occur. is there.
