PURPOSE:To smooth drawing out of a film and to decrease the rubbing flaws thereof by forming the cylindrical body of the cartridge of a resin added with a lubricity imparting agent. CONSTITUTION:The cartridge constituted by forming a spool 1 and the cylindrical body 3 of the cartridge of the resin (e.g.: acrylonitrile/butadiene/styrene copolymer) contg. a light shieldable material (e.g.: carbon black) is made into the structure in which a phototight state is released in a camera. The cylindrical body 3 is formed of the resin added with the lubricity imparting agent (A). A silicone oil having a dimethyl polysiloxane structure is preferably used at 0.5 to 5wt.% of the weight of the resin as the component A. The cartridge which is small and lightweight, does not require a teremp material and does not flaw the film is thus obtd. |
