PURPOSE: A rotational vibrator is provided to limit the reciprocation of a rotator within a creation angle by including a stopper. CONSTITUTION: A lower case is combined with an upper case(10) to form an internal space. One end of a rotation shaft(30) is combined with the upper case. The other end of the rotation shaft is combined with the lower case. A rotator(70) of a half circle form is combined with the rotary shaft and is reciprocated inside the case. A stopper(110) limits the rotation angle of the rotator. |
