PURPOSE:To prevent the noise occurrence of the engine in the caption by actuating a balance shaft in such a range that an engine and a body resonate. CONSTITUTION:The rotation of a pulley 52 is transmitted to the balance shaft 21 of an engine through a clutch plate 42, thereby the balance shaft 21 being rotated. A solenoid 55 is drivingly controlled by the output signals from an engine rotational speed sensor 82 and a crank angle sensor 101. The balance shaft 21 is rotationally operated in such a range that an engine and body resonate. Therefore, it is possible to prevent the noise occurrence in balance between the arbitrary vibration with the power performance. |
