Camera module

摘要

A camera module includes upper and lower leaf springs having a stable load characteristic and a holder displaceably held by the leaf springs so that the holder can be stably displaced within a magnetic circuit. The upper spring 5 has an outer annular portion 5a, an inner annular portion 5b provided inside the outer annular portion 5a so as to be displaceable with respect to the outer annular portion 5a and attached to the holder 9, and a plurality of bridge portions 5c coupled between the outer annular portion 5a and, the inner annular portion 5b. The camera module further includes a bridge portion supporting member 4 for supporting a part of at least one of the plurality of bridge portions so that a load characteristic of the leaf spring can be changed. By rotating the bridge portion supporting member 4 in a clockwise direction, an overlapping part between the extending part 4c and the bridge portion 5c is increased according to the amount of the rotation so that a spring constant of the upper leaf spring 5 is apparently increased.
