Abstract
A lens moving device comprises a lens frame to which a lens is attached and a drive mechanism which moves the lens frame along the optical axis of the lens. An arm-receiving opening is formed in a connecting member provided on the lens frame. The drive mechanism has a motor, and an output shaft of the motor is connected to a feed screw, on which a nut is fitted. A moving member is integrally formed on the nut, and first and second arms are provided on the moving member. The first and second arms are inserted into the arm-receiving opening. The first and second arms are arranged in order along the line, in which the lens is moved. A spring force of the first arm is greater than that of the second arm.
