う欠点を有している。2. Description of the Related Art Conventionally, a radiator cooling fan for a rear engine bus is generally driven by a V-belt from an engine. However, in a rear engine bus in which a power unit including an engine is arranged in a direction in which the engine axis is orthogonal to the vehicle center axis, the distance between the cooling fan and the power take-out mechanism on the power unit side may vary depending on the radiator position. Depending on the direction, it becomes difficult to drive the V-belt.
Therefore, when the fan is driven by hydraulic drive using a hydraulic pump and a hydraulic motor, the degree of freedom in designing the arrangement position increases. However, in such a drive system, it is necessary to support the hydraulic piping midway, and the supporting mechanism transmits the pulsation of the hydraulic pressure generated by the hydraulic motor to the body side, so that vibration / noise, particularly low frequency so-called It has the drawback of producing sound.
