Each of the rolls (31) has a structured outer surface. Two pairs of rolls (31) are attached to the sides of axles (12) guided through openings (11) in the base (1). Each of the axles (12) has a straight central part and extensions (121) at both ends positioned in an obtuse angle to the central segment and causing the rolls (31) to perform an oscillating motion across the particular body area of the user.</p> |
