1. A rotation-retarding device (10) comprising a first member (12) and a second member (11) having rotational movement relative to each other to be retarded, the first member (12) comprising an axle (13) and the second member (11) comprising a housing (25) adapted to receive the axle (13) of the first member (12), and means (16, 24, 28) for retarding rotation by deformation of elastically deformable flexible material, characterized in that the retarding means (16, 24, 28) comprise at least a part of the wall (24) bounding the housing (25), of elastically deformable flexible material and comprising at least one working surface (28) of cam form, facing the axle (13) of the first member (12), and at least one projection (16) of rigid material on the axle (13) of the first member (12), adapted to cooperate with a working surface (28) associated therewith to retard the rotational movement with the resisting couple being adapted to the driving couple at each angular position.
