PURPOSE: A finger-pressure wheel absorbing an electromagnetic wave is provided to sharply reduce a driver's fatigue and to protect the driver from harmful electromagnetic wave. CONSTITUTION: In an injection molding of a wheel composed a wheel shaft(6), supports(5), and a wheel body, magnetic protrusions(2) and natural jade protrusions(3) are alternately disposed on some part of the outer periphery of a wheel body(1). An electromagnetic wave-absorbing protrusion(4) is disposed in the center of the wheel body. Therefore, excellent finger-pressure effect is given to a driver and the driver's fatigue is reduced sharply.
