せることがない。(Function) In the above structure, a heat insulating material is placed on a support member fixed to the outer wall of the tank, and a member to be fastened, for example, a collar iron plate, is placed on top of the heat insulating material so as to press down on the heat insulating material. Then, when the seal packing material and the washer are fitted onto the screw and the screw is tightened, the stopper comes into contact with the support member and the tightening is completed. As a result, the screw becomes integrated with the supporting member, but the screw and washer do not become integrated with the fastened member.
In other words, the screw and washer press the fastened member through the compressed seal packing material, in other words, the fastened member is soft fastened. At this time, the screw hole cross section of the fastened member is in contact with the stopper part.
Therefore, when the outer wall of the tank expands or contracts, there is some space between the washer and the fastened member through the seal packing material, so a part of the seal packing material will be more compressed. There is no possibility of deformation, cracking, or scattering of screws in the members to be fastened.
（実施例）
以下、この考案の一実施例を第１図に基づいて
説明する。(Example) Hereinafter, an example of this invention will be described based on FIG. 1.
この実施例の軟締結用ネジ１は、右ネジ部２の
直上に、右ネジ部２とは反対方向の左斜線の凹凸
