- the fixing member 11 in FIG. 2 is H steel.
- the fixing member 11 is fixed to the hub 5.
- the fixed end of the structural beam 10 (the end on the fixed portion 12B side) is fixed to the fixed member 11 in the region where the structural beam 10 and the fixed member 11 overlap with each other by bolts and nuts 12B-1 and 12B-2. .
