Auxiliary device for turning horizontally lying persons and for mounting e.g. on a bed, the device including one or more largely vertically displacing devices that may be manipulated in vertical direction by means of a control panel, each device including a largely horizontally arranged roller which is rotatably secured at each end in a rotatable bushing, and the each rotatable bushing is fastened on first member, the first member being concentrically and displacing arranged in a second member, and means are provided by which impulses from the control panel can displace the first member relatively to the second member uniformly at both ends of the roller, which thereby may be moved vertically.
