PURPOSE: To prevent the occurrence of film rewinding fault on a photographic film cartridge in which a cover member and a disk are used. CONSTITUTION: A rib 50 having a curve part 50b whose radius is between radius Rf on the outermost periphery of the photographic film 6 in the case the film 6 is entirely wound inside a cartridge main body 5 and the radius Rd on the external periphery of the disk 17, for example, the radius Rr is integrally provided in the vicinity of the disk 17 on the internal wall of an upper case 3 so that at least one part of which is positioned within the range of an angleθ. Since both ends of the film 6 abut on the rib 50 and the film 6 is surely housed inside the lip 17a of the disk 17 in the case of rewinding the film, the photographic film rewinding fault does not occur.
