PURPOSE: Structure for improving the wrap angle of a power steering oil pump pulley is provided to enhance the driving efficiency and to reduce the slip noise by reducing the belt slip. CONSTITUTION: Tensioners(6) are installed between an alternator pulley(2) and a water pump drive pulley(4) and between an air conditioner compressor drive pulley(3) and a power steering oil pump pulley(1). The tensioners apply tensile force to a belt(5). To adjust the angle of the belt wrapping the oil pump pulley over 180 degrees, a second power steering oil pump pulley(10) is prepared. A second water pump drive pulley(11) is prepared. A power steering oil pump drive belt(12) is installed in the second power steering oil pump pulley. A second tensioner(13) is installed at a side of the power steering oil pump drive pulley. The second water pump drive pulley rotates the second power steering oil pump pulley via the power steering oil pump drive belt. According to the wrapping angle over 180 degrees, belt slip is reduced.
