PROBLEM TO BE SOLVED: To secure the degree of freedom in the design of camera, to make easy to form a yoke and to facilitate the assembly in a lens driving device using what is called a linear actuator. SOLUTION: In this lens driving device where a driving coil 15 provided in the movable lens part 4 of a camera is moved in the optical axis direction X-X by a magnetic circuit 17 constituted of a magnet 20 and the yokes 18 and 19, the circuit 17 is arranged at a position far from the optical axis of the camera and the shaft-like yoke 19 being one part of the circuit 17 is set as a guiding part for guiding the cylindrical driving coil of the movable lens part. |
