A pinch roller type tape drive assembly which is one of the elements composing a tape driving system of a VCR and ensures stable running of a tape. The pinch roller type tape drive assembly has a capstan for rotating at a constant velocity and a pinch roller which self-aligns, for pressing a tape against the capstan so as to drive the tape at the constant velocity together with the capstan. When the pinch roller is pressed against the capstan, an annular self-aligning member disposed between an inner sleeve and an outer sleeve is compressed in the direction of the contact point of the capstan and the pinch roller toward a pinch roller shaft, thereby holding the gap between the capstan and the pinch roller. Accordingly, the tape which is pulled and driven by the capstan and the pinch roller runs in a correct direction,
