The invention relates to a device comprising two members having rotational movement relative to each other to be retarded, of which the first member comprises an axle and the second a housing (25) adapted to receive the axle. This device is characterized by retarding means comprising at least a part of the wall (24) bounding the housing, of elastically deformable flexible material, and having, facing the axle, at least one working surface (28) of cam form, and at least one projection on that axle, adapted to cooperate with a working surface (28) associated therewith to retard the movement with the resisting couple being adapted to the driving couple at each angular position. Preferably, the first member is a rotor and each projection is a gadroon extending the length of a generatrix of the axle. Application for retarding rotational movement of an opening member, such as the lid of a make-up box.
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.
