PURPOSE:To prevent bending strain from being concentrated to one point, by gradually increasing width of a plate successively toward the welded end or successively increasing thickness of the plate and forming a stress dispersion absorption part on the upper part of an anchor strap. CONSTITUTION:A stress dispersion absorption part, increased its width successively in accordance with a location from the lower to the upper, is formed on the upper part of an anchor strap 6, and an upper side of the stress dispersion absorption part in said anchor strap 6 is performed butt welding in both sides 8 at a right angle with a loaded direction for a receiving mount 7, further this receiving mount 7 is welded to the surface of a side plate 9 of an inner tank 9. And the stress dispersion absorption part may be formed in such a manner that its plate thickness is gradually increased successively from the lower to the upper. The stress dispersion absorption part, being formed in the upper part of the anchor strap 6, linearly changes bending stress of the anchor strap 6 generated at cool down and operation, thus bending strain can be prevented from being concentrated to one point. |
