Abstract

A rolling ball hand-shaking exerciser comprises at least one main casing and one ball coated externally with soft material which rolls internally in the casing. The casing constitutes two identical semispherical shells interlocked integrally and extend outward to form tow handles. At the central beak of the shell a string of small pellets encircles one layer after layer with slightly projected head. When the player holds the handles and turns it around an orbit, the ball rolls in an inertia revolution manner with the limited space inside of the casing, it creates a vibration and damper action to achieve the hand exercise, and the pellets work as the massaging material as well.
