A spherical bearing mechanism consisting of a spherical face 5 formed on a surface of the inner support plate having a spherical body 6 slidably engaged with the spherical face. A rod 8 is installed in an opening 7 formed in at least one of the outer support plates, with its tip connected with the spherical body; and a straight motion bearing mechanism for back-and-forth movement of the rod is provided. There is also provided a multi-degree-of-freedom table mechanism, in which support units with the above structure are used to support a stage 14 on a support frame 13, so that the stage 14 can be moved in X, Y and Z directions by driving the rods of the support units back and forth.
