PROBLEM TO BE SOLVED: To provide a lens driving device where a stator and a driving magnet are arranged with high concentricity in the case of adopting constitution where a moving lens body is driven in an optical axis direction by coaxially arranging the stator and a rotating body equipped with the driving magnet rotated by the stator. SOLUTION: In the lens driving device 1, a projection 91 and recessed parts 92 and 93 are formed on the rotating body 8 and a rotary cam member 95 rotatable around a supporting shaft 94 is arranged on the side of them as a stopper mechanism 9 regulating the tolerance of the movement of the moving lens body. The rotary cam member 95 has the shape of a special Geneva drive whose plane shape is square, and an interference part 951 preventing the rotation of the rotating body 8, a recessed part 953 allowing the passage of the projection 91, and non-interference parts 952 and 954 interrupting the transmission of rotation from the rotating body 8 to the rotary cam member 95 itself are formed on the rotary cam member 95.
