Abstract:
A structure for holding a lens, the structure fitting a lens holding member holding a lens in an outer cylindrical member, the structure comprising:a biasing mechanism, located within the outer cylindrical member, adapted to bias the lens holding member, at least one of forward and backward in an optical axis direction;a plurality of engaging nails arranged on one of circumferential surfaces of the lens holding member and the outer cylindrical member, at substantially equal angular intervals circumferentially;a plurality of fixing holes arranged on the other of the circumferential surfaces of the lens holding member and the outer cylindrical member, at substantially equal angular intervals circumferentially to be respectively engaged with the engaging nails to retain the lens holding member relative to the outer cylindrical member against a biasing force of the biasing mechanism; andat least one tilt correcting plate selectively mountable between one of the engaging nails and mating one of the fixing hole to tilt an axis of the lens holding member relative to an axis of the outer cylindrical member.
