The case is equipped with a built-in motor rotating a motor shaft by electric power of a battery. The cylinder has one side connected to the motor shaft and is coaxially rotated with the motor shaft. The shaft has one end inserted into the cylinder and the other end provided with rectangular angle portion(50a). The abrasion member is connected to the angle portion of the shaft. The shaft fixing member is attached to both side of an upper surface of the case with regard to the cylinder, and holds the angle portion of the shaft.
