摘要： A lens drive device may include a movable body provided with a lens and a drive mechanism for driving the movable body in the optical axis direction. The drive mechanism may include a substantially triangular prism-shaped drive magnet part disposed in at least one of four corners of the lens drive device, and a drive coil wound around a substantially triangular tube shape and whose inner peripheral face is oppositely disposed to an outer peripheral face of the drive magnet part through a gap space. In at least another embodiment, a lens drive device may include a flat spring provided with a plurality of arm parts which connect a movable body fixed part with a fixed body fixed part. The arm part is formed with a low spring constant part whose spring constant is smaller than a spring constant of other portion of the arm part.

摘要： A lens drive device may include a front side spring member which is connected between a movable body having a lens and a support body. The front side spring member includes a support body side connecting part, a movable body side connecting part and a arm part connected between the support body side connecting part and the movable body side connecting part. The support body includes a yoke having a yoke front plate part and the yoke front plate part is formed with a yoke opening part which is overlapped with at least a part of the front side spring member. Damper material having viscoelasticity is provided, for example, on a portion extending over the movable body side connecting part and the arm part and overlapped with the yoke opening part in the lens optical axis direction. Therefore, the damper material can be applied to the front side spring member through the yoke opening part in the final stage of assembling steps.
