    摘要： There is provided a position control apparatus and method for a table member which is capable of controlling the positioning of the table through very small displacement thereof, to thereby prevent the position of the table from deviating even when a disturbance such as vibration is applied to the table. A table member is movable relative to the base member in a predetermined direction. A threaded shaft is rotatably mounted on a base member and elastically deformable when twisted. A motor is coupled to one end of the threaded shaft, for rotating the threaded shaft to displace the table member. A pressurizing and fixing member is arranged in the vicinity of a location where the motor is coupled to the threaded shaft, for pressurizing the threaded shaft to be fixed in position.
