Each massage roller comprises a main axis which can be fitted with a slider, into which may be formed the inner, annular grooves of the individual roller sleeves. The outer ring face of the sleeves locates several protruding members. A limiting fastener can be inserted into the free main axis end by its side tube. The individual groups of massage rollers are fitted between the opposite fastening holes of the supports, using the main axis and the side sleeves of the limiting fasteners. Then the supports and roller groups are interconnected by head screws and transverse shafts inserted into the axial bores of the supports.
