PROBLEM TO BE SOLVED: To reduce the number of parts and manufacturing cost by using one kind of joiner receiving member being common on corner step faces of a floor pan conveniently and freely on the left and right sides and improve stability and a storage condition in mounting of the joiner receiving member. SOLUTION: A rising piece extended part having substantially L-shape when viewed in a plane is provided by protruding from a side end part on a corner step face 6 side of a rising piece 5 in an upper loading part 3. When left and right fitting recessed parts 20 of the joiner receiving member 8 are fitted into the rising piece 5 and the rising piece extended part, respectively, and a lower side wall panel 9B is arranged adjacent to an upper side wall panel 9A on the right side, a locking part 15 of the lower side wall panel 9B is stored in a storage channel 21 on the right side of the joiner receiving member 8. On the other hand, when the lower side wall panel 9B is arranged adjacent to the upper side wall panel 9A on the left side, it is used conveniently and freely on the left and right sides to store the locking part 15 of the lower side wall panel 9B in the storage channel 21 on the left side of the joiner receiving member 8.
