ABSTRACT:
The present invention relates to an improvement in an image-shake correcting device which has a light deflecting unit having two opposed surface portions and a bag-like structure filled with a liquid having transparency, the light deflecting unit deflecting light passing therethrough by inclining at least one of the two surface portions. In the aforesaid device, there is provided a supporting member for supporting the at least one surface portion of the light deflecting unit while allowing the at least one surface portion to swing around an axis, each of the two surface portions being a substantially equal distance from the axis. Accordingly, it is possible to prevent a reaction force from occurring on a bearing located on the swinging center axis of the surface portion and increasing driving load.
