Abstract
A hand-shaking exerciser outfitted with an internal rotor comprises a hollow casing and a rotor shaft. The hollow casing consists of two identical semispherical shells interlocked integrally and extending outward to form two handles. At the far top of the shell, many small hard pellets are installed. The internal inertia rotor shaft is composed of two crown plates, an inertia weight and a wheel plate, one of which has an oval head at one side and one sleeve at other to receive the inertia weight. Two crown plates will hold and lock the inertia weight and wheel plate firmly to constitute an integral rotor shaft. When the player holds the handles and shakes the exerciser, the rotor shaft will make a free inertia rolling within the casing. The vigorous rolling of the rotor shaft will produce powerful vibration force acting as a massaging force to achieve the practical purpose.
