ABSTRACT:
A pair of flanges are mounted on a spool of a photographic film cassette so as to come into contact with end faces or outermost convolution of a film roll wound on the spool, so that a film leader can be advanced out of the cassette shell by rotating the spool in an unwinding direction. The flanges are formed from a polyphenylene ether group resin composition, which is composed by mixing styrene group resin with polyphenylene ether resin in a weight ratio from 60:40 to 10:90, and mixing 6 to 19 parts by weight of elastomer per 100 parts by weight of said mixture of styrene group resin and polyphenylene ether resin.
