Abstract
A supporting unit in a moving table device, easily connected to a base and a table, is provided. A supporting unit (Uα) has a pair of planar bearing plates. Inside the planar bearing plates are positioned spherical bearing plates, respectively. Further, a spherical axial member is sandwiched between the spherical bearing plates (). A planar bearing is formed between each of the planar bearing plates and each of the spherical bearing plates. A spherical bearing is formed between each of the spherical bearing plates and the spherical axial member. Thus, the supporting unit (Uα) is provided with a certain degree of movability in five-axis directions. With the high degree of movability, the supporting unit (Uα) can be easily connected to a base and a table.
