A lens supporting frame is provided and includes a lens holder supporting a lens and a moving frame which is fitted to a cylindrical part of the lens holder to support the same. Ribs are provided at equal intervals in a rotation direction on a rear end face of the lens holder, the ribs having a plurality of inclined surfaces inclined respectively toward the front or rear ends of an optical axis. Abutting parts are provided on a rear end face of the moving frame so as to abut on the ribs. When the lens holder is rotated after mounting it in the moving frame, parts of the lens holder facing the abutting parts are moved in directions along the optical axis as a result of abutment between the inclined surfaces of the ribs and the abutting parts to change the inclination of the lens holder relative to the optical axis.
