Abstract
An interlock ring is provided to transmit a rotational force of a casing of a lens unit to a attachment ring, and contact faces of a projection of the attachment ring and a projection of the interlock ring are slant. Thereby, the stress is prevented from concentrating at the base corners of the projections. Thus, the projections can be prevented from breaking due to over-fastening.
