<p>PROBLEM TO BE SOLVED: To expand the variable ranges of coupling angles by coupling a junction member and fitting members via spherical sliding structures, forming the spherical sliding structures to pinch two spherical seats where the spherical walls of the fitting members on the junction member, and removably supporting the spherical seats on support columns penetrating the through holes of the spherical walls. SOLUTION: Fitting members 2, 3 are fastened and fixed to the coupling ends of coupled members A, B by screws 5. Spherical packings 612 of spherical seats 61 of a spherical sliding structure are coupled with the openings 12 of a junction member 1, joint parts 22, 32 of the fitting members 2, 3 are brought into contact with the spherical packings 612, and spherical dishes 611 of the spherical seats 61 are coupled and fastened to support columns 13 of the junction member 1 by set screws 4 from the inside of the joint parts 22, 32. The joint parts 22, 32 are screwed to the fixing sections 21, 31 of the fitting members 2, 3. Coupling angles of the coupled members A, B can be three-dimensionally changed, and the variable ranges of the coupling angles can be expanded more than the two-dimensional change. Execution is mainly made via contact and screwing, the coupling/disassembling work is facilitated, and the action is made reliable and smooth.</p> |
