ABSTRACT:
A lens and a lens holding device make it possible to construct a compound lens or to secure a lens to a lens barrel by providing protrusions and/or depressions on a joint surface or surfaces of a lens and/or a lens contact surface of a lens barrel and interconnecting the protrusions and the depressions. Particularly, the protrusions and/or the depressions are provided with undercut areas and at least one of the protrusions and the depressions to be combined are formed so as to be elastically deformable to prevent them from separating after interconnected.
