The invention relates to a seal for a gap between a rotatable shaft (3) and an element (1) surrounding the shaft. The seal comprises a lid (5) provided on the surrounding element and showing an annular groove (6) which is open towards the envelope surface of the shaft, and a resilient ring (7) provided on the shaft, which ring is enclosed by the groove. One end surface (8) of the ring is covered by a flock of fibres (10). The free ends of the fibres contact one of the groove walls. The other end surface (9) of the ring directly contacts the other groove wall.
