PURPOSE:To fix an upper stage linking tool assuredly without slipping to a lower stage linking tool even when an outside force is added to the upper stage linking tool in the lateral direction by a method wherein a groove shaped part to be fitted of which the lower surface is open is formed on both members to be supported, and a fitting member is provided at the upper end of a front vertical member. CONSTITUTION:A lower frame 1 is formed of both members to be supported 2a, 2b and a rear lateral member 3, and a top frame 4 is connected on the top of the lower frame 1 by front vertical struts 5a, 5b and rear vertical struts 6a, 6b. A groove shaped part to be fitted of which the lower surface is open is formed on members to be supported 2a, 2b, and a fitting member 17 is provided at the upper ends of the front vertical struts 5a, 5b. A pair of right and left stopper bodies 25a, 25b are provided on the rear surface of the top frame 4, and detachable protruding parts 26a, 26b are provided between both stopper bodies 25a, 25b for a lower stage carrying tool on the rear surface of the rear lateral member 3. Therefore, linking tools are stacked, the groove shaped part to be fitted on an upper stage carrying tool is fitted in the fitting member 17 of a lower stage carrying tool, and also the protruding parts 26a, 26b of the upper carrying tool are fitted between the stopper bodies 25a, 25b of the lower stage carrying tool. |
