Abstract
A photographic film cassette has a photographic film leader, which is advanced outwardly from a cassette shell when a spool is rotated. The spool has two flanges, of which a first one is loosely fitted on a core of the spool. A circumferential lip projects from an inside surface of the first flange toward a photographic filmstrip, contacts on a lateral side of a roll of the filmstrip, and prevents the roll from loosening. The first flange together with the lip is formed according to thermoforming from a sheet of thermoplastic resin having a melt index of 4 or less so as to have a high intensity, and has a thickness of 0.4 mm or less so as to be deformable with a small force.
