To provide a movable member moving apparatus capable of driving a movable member in an arbitrary direction (straight-line direction and rotation direction) within a two-dimensional plane using a simple mechanism.

The movable member for moving apparatus is composed of at least three unidimensional drive mechanisms 3a-3c, displaced in a unidimensional direction and a control part 4 for independently calculating the displacing direction and displacement quantity of the respective unidimensional drive mechanisms 3a-3c and the respective unidimensional drive mechanisms 3a-3c come into contact with the under surface 1s of the movable member 1, to support the movable member 1 so as to move the contact position with the movable member 1 on the basis of displacing action. The displacement directions 2a and 2b of at least two unidimensional drive mechanisms are made to direct to different unidimensional directions within the two-dimensional plane, to make the movable member 1 move by the same unidimensional drive mechanism to rotate and go straight ahead.
