PROBLEM TO BE SOLVED: To manufacture many types of lens-fitted photo film units by setting photographing conditions such as the focal position of a lens, a diaphragm aperture and shutter speed on one part and replacing only the one part. SOLUTION: A stopper 50a, a diaphragm aperture 50b, a lens receiving portion 50c and a lens cover locking claw 50e are formed on a lens base 50 in one. The stopper 50a comes in contact with a shutter blade 40 when the shutter blade turns in an opening direction, thereby controlling the maximum turn amount. The diaphragm aperture 50b controls the light quantity of subject light which reaches a photo film through a taking lens 60. The lens receiving portion 50c positions the taking lens 60 in an optical axis direction. The lens cover locking claw 50e locks a lens barrel 50d which houses the taking lens 60 and a lens cover 70 which is attached to the anterior end of the lens barrel 50d to hold the taking lens 60 between the lens cover and the lens receiving portion 50c.
