<P>PROBLEM TO BE SOLVED: To provide a lens drive device in which the twisting workability of a compression coil spring is excellent. <P>SOLUTION: In a lens drive device, that is, the lens drive device 1, for applying a twisting return force around a guide shaft 10 to a lens holder 8, one end of a compression coil spring 11 is caught on a guide shaft 10 and the other end of the compression coil spring 11 is caught on the lens holder 8, When such a constitution is adopted, the guide shaft 10 is only rotated when applying a twisting force to the compression coil spring 11 and further, the number of rotations of the guide shaft 10 corresponds to the number of twists of the compression coil spring 11, so that the number of twists and twist angle of the compression coil spring 11 can be freely and easily adjusted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
