PURPOSE: A subsidiary output shaft is provided to increase productivity and save oil by using surplus force of rotating force for an output shaft in order to give vibration force to the other vibrator. CONSTITUTION: A vibrator(105) removes mortar bubble by vibration when inserted into mortar. A driving pulley combined with an output shaft(102) rotates belt. The belt rotates an interlocking pulley and then a subsidiary output shaft(104) rotates by connecting with the interlocking pulley. The number of rotations is increased or decreased by freely setting the size of the driving pulley, the interlocking pulley, a driving gear, an interlocking gear or a driving sprocket and an interlocking sprocket. Thus, the other vibrator also removes mortar bubble by connecting with the subsidiary output shaft.
