Abstract
Abstract The massaging apparatus comprises a relatively large number of massaging balls or beads all of which are supported in a planar fashion between a double-walled support structure. One wall of the support structure has bead-positioning cavities and the other wall has openings through which the beads extend. The majority of the beads are of a first, smaller size while a relatively few beads, located along a central axis, are of a larger size. The apparatus preferably has support straps to support the apparatus from an automobile seat; the massaging device being usable by an automobile operator to relieve back ache or strain especially during a long trip.
