First and second clutches allow first and second tubular output shafts to pivot when a motor generates rotation at a second rotation speed or higher. A third clutch allows a pivot shaft to pivot when the motor rotates at a speed lower than a first rotation speed. A control plate is arranged at a first pivot position, second pivot position, or third pivot position. At the first pivot position, the first and second tubular output shafts are moved to positions in an axial direction allowing first and second rotated members to rotate. At the second pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the first rotated member to rotate. At the third pivot position, the first and second tubular output shafts are moved to positions in the axial direction allowing only the second rotated member to rotate.
