PROBLEM TO BE SOLVED: To prevent a noise or the like in driving and to perform accurate feeding operation in a lens driving device using a lead screw and a nut. SOLUTION: The lens driving device is equipped with a lead screw 71, a nut 73', a lens holding frame 51 moving integrally with the nut 73', and a nut bearing part 52 provided in the frame 51 so as to regulate the rotation of the nut 73'. The bearing part 52 has a fitting recessed part 52a in which the projecting part 73b of the nut 73' is fit, and a cushioning member 52b coming into contact with the projection part 73b around the axial center of the screw 72 is stuck to the recessed part 52a. Thus, the noise or the like caused by the deflection of the screw 71 is prevented and accurate positioning is realized. COPYRIGHT: (C)2004,JPO
