摘要： PROBLEM TO BE SOLVED: To provide a highly reliable base isolating device for a middle column of an underground structure which allows a pin structure to be easily formed at low cost on the floor face and ceiling face of the underground structure and at the upper and lower ends of the middle column to protect surfaces of contact, thus assuring the long-term sliding property of the surfaces of contact. SOLUTION: This base isolating device 20 is mounted on at least one of the upper and lower ends of a middle column 10 erected between the floor part and the ceiling part of a cylindrical underground structure to provide support between the floor part and the ceiling part, and comprises a middle-column-side member 21 and an underground-structure-side member overlapping each other. The middle-column-side member 21 and the underground-structure-side member have respective base parts 22 and contact parts formed into curved shapes that project in opposite directions from the base parts and can be fitted in each other on their surfaces of contact, and the members also have a rubber-elastic body interposed between the base parts on both sides along the direction in which the contact parts can slide. The rubber-elastic body is formed by vulcanization bonding process and may be in the form of an annulus surrounding the peripheries of the contact parts. The surfaces of contact may be provided with friction-reducing members.
