<p>A massaging machine (1) has massaging balls (402a-d), ball supporting arms (403R,403L) for supporting these massaging balls, a first rotary shaft (510) and a second rotary shaft (410) that have mutually parallel axes of rotation at different heights, an eccentric part (520) on the first shaft that is eccentric with respect to its axis of rotation, a sloped part (420) on the second shaft that is sloped with respect to its axis of rotation, a support arm with one end part attached to the ball supporting arm and the other end part attached to the sloped part, and a link that connects the eccentric part with the support arm. The support arm has a bearing with a spherical surface. The link has a spherically shaped end part that engages with the bearing. The ball supporting arms are attached to the support arm at a height between the heights of the first and second rotary shafts. <IMAGE></p> |
