Each of the first, second and third tables includes a bent section formed with a guide groove, and two associated guide grooves of any adjacent two of the tables are located opposite to each other to define a guide groove in which a plurality of rolling members are provided. Thus, a linear relative motion can be provided between the first and second tables in X direction, and another linear relative motion can be provided between the second and third tables in Y direction.
