Abstract

PROBLEM TO BE SOLVED: To support a case more stably by providing a ground base integrally formed below a spherical bearing part for holding a spherical body part slidably with the center of a support as a fixed position, and a box nut mounted on the spherical bearing part so as to pressure-lock the spherical body part. SOLUTION: A stable supporting device 10 consists of a support, a ground base 2 and a box nut 3. A spherical bearing part 21 holds a spherical body part 12 slidably with its center as a fixed position, and the upper end of a shaft part 11 is adjusted in its vertical position and fitted to a case 5 by a fitting means. At the time of installing the case 5, a grounding bottom face part is conformed to the shape of the ground plane so as to be able to temporarily fix the case 5 in a nearly horizontal state. The spherical body part 12 is pressure-locked to the spherical bearing part 21 by the box nut 3. The shaft part 11 is therefore put in a fixed state to the ground base 2, so that the case 5 is supported in a stable state.
