The fixture is attached to the stud bolt that is welded in the gap, and the panel is fixed to the outer surface of the tank for low temperature cargo by this fixture, so it is not necessary to drill holes in the panel as in the past. Eliminates the installation troubles caused by the gap between the panel hole position and the stud bolt welding position on the outer surface of the low temperature cargo tank,
The work of attaching the panel to the outer surface of the low-temperature cargo tank can be facilitated, and the work efficiency can be improved and the work cost can be reduced.

It is possible to prevent lateral displacement. Moreover, it is possible to prevent the panel from being lifted from the outer surface of the low temperature cargo tank by pressing the upper surface of the end of the panel by the brim formed on the upper edge of the hollow body, and further, the long hole formed on the bottom surface of the hollow body. Even if there is an error in the welding mounting position of the stud bolt, the bolt mounting hole can absorb the error and mount the mounting tool with high accuracy, which is a very new and beneficial effect.
