Abstract

Bolt bores in lower members each comprise a large-diameter portion larger than the head of a bolt in diameter, and a small diameter portion extending downward from the large-diameter portion with a stepped portion formed therebetween and having a diameter intermediate between the diameter of the bolt head and the diameter of the shank of the bolt. A heat insulator has a spacer inserting hole. A hollow cylindrical spacer having an inside diameter larger than the diameter of the bolt shank is inserted through the small-diameter portion of the bolt bore and the spacer inserting hole so that the upper end of the spacer is positioned in the large-diameter portion. The spacer has a lower end bearing on a support member. A hollow cylindrical elastic member is interposed between the bolt head and the stepped portion for biasing the lower member toward the support member.
