As shown in FIG. 7, the mechanism for transmitting the load on the main body column 11 side to the temporary receiving members 13, 13 by the brackets 12, 12 protruding from the main body column 11 is shown in FIG. As shown, when the main body column 11 is tilted by the tilt angle θ, the clearances L1 and L1 between the members 12 and 13 shown in FIG. 7 are the clearances L2 and L2A (L2 <L
2A). Further, as shown in FIG. 9, the bracket 1
When there is a deviation in the height of 2 or the temporary receiving material 13, the clearance changes to L3, L3A (L3 <L3A). in this way,
If the clearance becomes non-uniform, the load transmitted to the temporary receiving members 13, 13 becomes non-uniform, which is not preferable. Therefore, conventionally, the clearance is corrected by using a steel filler plate or the like.
