PROBLEM TO BE SOLVED: To prevent chipped damage to a sliding face of one of slide boards corresponding to a machine screw hole for holding a screw of the other slide board. SOLUTION: In this base-isolating device, round chamfering is applied to a surface edge part 22a1 of a machine screw hole 22 for holding a screw opened on a sliding face 5a (6a) of each of slide boards 5 (6) of a sliding support part 4. According to this base-isolating device, the sliding face 6a of the other slide board 6 dents into the machine screw hole 22 opened on the sliding face 5a of one of the slide board 5, and when the slide boards 5 and 6 mutually slide, the surface edge part 22a1 of the screw machine hole 22 smoothly slides on the sliding face 6a of the other slide board 6. Thus, there is no nonconformity that the sliding face 6a of the other slide board 6 is chipped by the surface edge part 22a1 of the machine screw hold 22. COPYRIGHT: (C)2003,JPO
