ABSTRACT:
An image vibration reduction device has a vibration reduction optical system movable for reducing an image vibration, a guide member for movably guiding the vibration reduction optical system in a predetermined direction, and a driving force generating device for generating a driving force for moving the optical system. Disposed on substantially the same plane are a centroid of the whole movable portion including the vibration reduction optical system moved when reducing the vibration, a portion where a load is produced between the movable portion and the guide member, and a position where the driving force of the driving force generating device is generated. A moment produced due to a disposition positional deviation can be thereby restrained.
