<p>PURPOSE: To obtain a molding excellent in the sliding properties on a tape and other physical properties and suitably employed as a guide or post for traveling a magnetic tape by specifying the surface resistance and the average roughness on the center line. CONSTITUTION: The molding for tape sliding member is composed of polyallylene sulfide resin or liquid crystalline polyester resin composition mixed with 10-50wt.% (for the composition) of carbon fibers. The molding has surface resistance of 10<7>Ωor below and roughness on the center line (Ra) in the range of 0.5-10.0μm. Preferably, the resin composition further contains 5-40wt.% of talc or 5-30wt.% of fluororesin. This composition realizes a traveling post or guide having excellent characteristics in which the coefficient of friction is settled at a low value over a long time use from the initial stage, the tape and other members are protected against damage and trouble due to staticelectricity is eliminated.</p> |
