The motor bracket(18) is mounted on one side of a driving motor(4) and has multiple bolt inserting grooves formed on the both sides thereof. The guiding bracket(20) is fixed on a case(10) and has multiple guiding grooves vertically formed on the both sides thereof perpendicularly to the driving motor(4). The adjusting bolts(24) are inserted between the motor bracket(18) and the guiding bracket(20) and are tightened after moving the driving motor(4) perpendicularly to adjust the tension of a belt(6) to fix the motor bracket(18) and the guiding bracket(20).
