摘要： An alternator includes a rear-end fan which is constructed so as to have greater capacity than a front-end fan. The construction is such that a flow rate in a front-end ventilation pathway in which a cooling air flow enters through front-end air intake apertures is deflected centrifugally by the front-end fan and is then expelled through front-end air discharge apertures is greater than a flow rate in a rear-end ventilation pathway in which a cooling air flow enters through rear-end air intake apertures is deflected centrifugally by the rear-end fan and is then expelled through rear-end air discharge apertures.
