<p>PURPOSE:To save the space and simplify the assembly and decomposition in the lens barrel when a shake preventive mechanism part, etc., is incorporated and to increase the diameter of a lens by securing an optical system space. CONSTITUTION:The lens barrel is equipped with a shake prevention optical system L3 which is moved in a plane perpendicular to the optical axis I of a main optical system to prevent image shake and an image shake preventive driving mechanism 30 (30X and 30Y) which drives said optical system. This image shake preventive driving mechanism is arranged at the periphery of the shake prevention optical system without overlapping with other mechanism. Further, a transmission shaft 17 (17b) for a driving force to a focusing mechanism part arranged in front of the shake preventive mechanism is arranged without overlapping with the image shake preventive driving mechanism arranged at the periphery of the shake prevention optical system.</p> |
