ABSTRACT:
Disclosed are slide members for parts to be in contact with magnetic tape, which are made of polyarylenesulfide resin compositions comprising from 20 to 40% by weight of a polyarylenesulfide resin optionally combined with an amorphous, thermoplastic resin, and from 60 to 80% by weight of calcium metasilicate whiskers having a mean fiber diameter of not larger than 5 .mu.m and a mean aspect ratio of not smaller than 5, optionally combined with an inorganic filler. While being shaped, the resin compositions have good fluidity. The slide members are used in electric and electronic devices as the parts to be in contact with magnetic tape, for example, as VTR cylinders (drums). The slide members have high mechanical strength and good dimensional stability, and have good slidability with magnetic tape.
