PROBLEM TO BE SOLVED: To provide a lens actuator used mainly for a camera and a cell phone, the lens actuator capable of reducing generated noise due to abrasion of a shaft.SOLUTION: When a lens holder 21 is moved in the direction of the optical axis OA of a lens relative to a fixed unit 24, tensile force of wires 22A, 22B decreases pressing force with which the lens holder 21 is pressed against a shaft 34 by springs 23A, 23B, and the lens holder 21 is moved by using the tensile force of wires 22A and 22B, so that the noise generated due to abrasion of the shaft 34 is reduced. |
