An imaging device includes an image-shake detector for detecting vibration applied to a photographing optical system; first and second movable frames, for supporting an image-stabilizing optical element, which constitutes a part of the photographing optical system, so as to be movable in two directions different from each other in a plane orthogonal to a common optical axis of the photographing optical system; first and second biasing devices for biasing the first and second movable frames in the respective moving directions thereof; first and second stopper devices for determining movement extremities of the first and second movable frames, respectively, in respective biasing directions of the first and second biasing devices; and a driving device for counteracting image shake by driving the first and second stopper devices in accordance with an output of the image-shake detector to thereby move the first and second movable frames, respectively.
