intake port of the rear bracket 2 passes through the rear-bracket-side heat sinks 24, 24 of the rectifier device 12 and a vent hole formed facing the regulator heat sink 19 to cool the rectifier device 12 and the regulator 20.
The cooling air cools the rectifier device 12 and the regulator 20 while passing through them, and is then directed in the centrifugal direction by the rear-bracket-side fan 5 to cool the rear-bracket-side stator coil end so as to be discharged to the outside through a bracket exhaust port.
Moreover, the cooling air drawn in the axial direction from the front-bracket-side intake port is directed in the centrifugal direction by the fan 5 to cool the front-bracket-side stator coil end and then discharged to the outside through a bracket[Microelements balance and correction in athletes++ under high muscular load].
The balance studies among the high-qualified adult sportsmen during the winter period of practices had shown that of the day of a 30-km cross the contents of iron, copper and manganese in the food ration fell to the lowest level of the physiological standard of people not going into sports due to sufficient physical load the process of microcomponents' secretion through bowels and kidneys was outstripping their replenishment from food. The balance of all three microcomponents was negative. During the following three days after the cross due to disbalanced food ration caused by the content of microcomponents the losses of iron and copper were not compensated. The enrichment of the food rations by the set of components caused the
