PROBLEM TO BE SOLVED: To constitute an angle adjustment device at low cost, which adjusts the angle of a surface to be adjusted, with good responsiveness, easiness in operation and a simple circuit structure. SOLUTION: This device comprises three actuators 12A, 12B, 12C which operate in response to an input signal and apply force against the surface 10 to be adjusted, and three displacement detectors 14A, 14B, 14C which detect the displacement of the surface 10 to be adjusted. Three displacement detectors 14A, 14B, 14C are arranged respectively such that when one of the actuator of the three actuators 12A, 12B, 12C is operated, two of the displacement detectors are arranged on the center axis of impact for application of the force and that only one of the displacement detectors is arranged at a place other than the center axis of impact.
