Magnetic-field dependence of the resistivity for various currents in the layered superconductor 2H-NbSe[sub 1.8]S[sub 0.2] was investigated. The flux flow was observed for various angles between the magnetic-field direction and the crystal layers near zero-field critical temperature. Anisotrophy of the pinning force and the viscosity coefficient was found. The peak effect was observed under a magnetic field perpendicular to the layers. A strong pinning force was found acting only on flux lines parallel to the layers. These results can be explained by the pinning mechanism due to the stacking faults.
