An optical element (e.g. camera lens) position control mechanism (e.g. actuator) comprises an optical element holding member 51 for holding an optical element LG3 which is moveable in an optical axis direction (O, figure 1); an advancing and retracting movement guide member 52 (a guide shaft) for guiding the optical element holding member 51 in the optical axis direction; and a biasing device, spring 38 including an arm 38c, the arm being rotatable or swingable about a pivot axis which is substantially orthogonal to the optical axis wherein said biasing device simultaneously exerts via said arm both a biasing force in the direction of movement of the optical element holding member and a biasing force in a direction orthogonal to the direction of movement of the optical element holding member. |
