<p>The device contains massaging elements as balls (6), where a rotatably embedded shaft (5) is connected through geared down drive (4) of 50-85 r.p.m. output speed with the driving motor (3), where the ball or balls (6) are eccentrically fixed, and a footrest (9) is formed along their path. The balls (6) are evenly spaced along a circle in the plane or planes perpendicular to the shaft (5), for example they are fixed to the shaft (5) with radial pins (8) secured against turn around their own axis.</p> |
