Abstract: In order to attach a lens hood to a lens body while positioning the lens hood, fixing convex portions are provided on the lens hood and fixing uneven portions are provided on the lens body. On the fixing uneven portion of the lens body, a positioning slope coming into contact with the fixing convex portion of the lens hood upon attachment is provided on a position where a convex portion and a recessed portion are continuously formed on the lens body. Thus it is possible to facilitate attaching and detaching with a simple configuration while obtaining placement accuracy in the circumferential direction of a lens and in a thrust direction.

Abstract: In order to attach a lens hood 100 to a lens body 200 while positioning the lens hood 100, fixing convex portions are provided on the lens hood 100 and fixing uneven portions 204 are provided on the lens body 200. On the fixing uneven portion 204 of the lens body 200, a positioning slope coming into contact with the fixing convex portion of the lens hood 100 upon attachment is provided on a position where a convex portion and a recessed portion are formed continuously on the lens body 200. Thus it is possible to facilitate attaching and detaching with a simple configuration while obtaining placement accuracy in the circumferential direction of a lens and in a thrust direction.
