A massager with a vertical guide column (1) which has a cylinder/piston unit (10) and toothed racks (4) mounted at the side on the guide column (1). These toothed racks (4) engage pinions (5) which hold the brushes (7) which are mounted in housing halves (8) which slide up and down on the guide column (1). The housing halves (8) are connected by connecting rods (12) and a crossbar (11) to the piston rod (9) of the cylinder/piston unit (10). With the help of a control valve (15), automatic switching to the end positions of the brush unit can be achieved.
