Summary:PROBLEM TO BE SOLVED: To provide a lens device that enables adjustment of the eccentricity of a lens barrel while checking an image, without increasing the size of a structure. SOLUTION: The lens device includes: the lens barrel holding an optical system, and a support means supporting the lens barrel. The support means is supported by the body of the lens device so as to be rotatable around a pivot as a support pivot provided outside an optical path. At a position different from the support pivot of the support means, the lens barrel is held so as to be rotatable around a pivot as a pivot of the lens barrel on a flange provided integrally with the lens barrel. The support means is provided with a tool-attaching portion for attaching, so as to be freely attachable and detachable, a tool, which is inserted from the opening provided on the body of the lens device and which used to rotate the lens barrel around the pivot of the lens barrel with respect to the support means. The face of the flange is provided with a lens barrel engagement portion for engaging the tool. COPYRIGHT: (C)2011,JPO&INPIT
