Abstract
A vibration-preventing device for a main optical system which prevents the occurrence of image shake due to vibration. A vibration-preventing optical system is held by a lens frame and moves in a direction at a right angle with respect to an optical axis of the main optical system to prevent the occurrence of image shake due to vibration. Moving members are joined to the lens frame and are driven in a direction which is at a right angle with respect to the optical axis. A guide determines a direction in which the moving members are driven and an energization device is attached to the lens frame and energizes the lens frame to contact the moving members.
