Abstract
In a massaging apparatus (1) comprising a suction chamber (12) bounded by chamber walls (13, 14, 15, 16) and a pump (19) for the generation of a partial vacuum inside the suction chamber (12) and thus forming a skin fold (20) which is drawn into the suction space inside the suction chamber (12), as well as two rollers (21, 22) to be placed onto a body area (3), the two rollers (21, 22) can be driven by a motor (27) via a drive transmission (28), and the roller (21) which is disposed at the front, as viewed in the operating direction (4), is arranged inside the suction chamber (12), and the roller (22) which is disposed at the rear, as viewed in the operating direction (4), is arranged outside the suction chamber (12), the circumferential surface (25) of the roller (21) which is disposed at the front, as viewed in the operating direction (4), advantageously consisting of a material having a friction value higher than that of the material of the roller which is disposed at the rear, as viewed in the operating direction (4).
