A lens holding frame holding a lens having a circular outer diameter includes a first holding member forming an inscribed circle corresponding to the outer circumference of the lens and a second holding member forming a larger inscribed circle than the inscribed circle formed by the first holding member. The first holding member comprises three projections and they are located at an equal distance in the circumferential direction of the lens holding frame. Similarly, the second holding member also comprises three projections and they are located at an equal distance in the circumferential direction of the lens holding frame. In this case, the projections forming the first holding member and the projections forming the second holding member are located alternately on the inner diameter of the lens holding frame in the circumferential direction respectively. Further, the projections composing the second holding member are composed so that they will form a larger inscribed circle than the inscribed circle formed by the projections composing the first holding member.
