PROBLEM TO BE SOLVED: To provide an angle adjustment device that has low slidability, that can be miniaturized, and that is clean. SOLUTION: The movable table 2 is supported in a floating state with a magnetic fluid 6, assuring infinitely lower slidability between the movable table 2 and a base 3. In addition, since the device is merely given a structure in which the magnetic fluid 6 is held between the movable table 2 and the base 3, there is no need of other members, making miniaturization possible for the device.
