４を加熱するという不具合を生じる。However, there is a possibility that muddy water or the like may enter through the air intake ports 5a-1 and 5a-2 on the wind and adhere to and accumulate near the diode 4. For this reason, the fan guide 6 is provided with a notch 6a for discharging muddy water (see FIG. 3). By providing the notch 6a in this manner, the muddy water flowing near the diode 4 flows further down and is discharged from the exhaust port 5b. but,
If the above-mentioned notch 6a is provided, a part of the air blown by the fan 2aK in the direction of the arrow A is diverted and flows backward as shown by the arrow B, causing a problem that the diode 4 is heated.

とする。The present invention, which was created to achieve the above object, has a cooling fan fixed to the side surface of the rotor core, a rectifier installed on the inner surface of the housing, and a rectifier placed opposite to the blower fan inside the housing. The present invention is applied to a vehicle alternator in which a fan guide is installed on the side of the fan, and the vicinity of the lower end of the fan guide is formed into a shape that bulges toward the fan side, and a part of the bulge faces the outer periphery of the fan. K. The outer periphery of the bulging portion faces the cooling ventilation exhaust port.

下する。With the above configuration, the air blown by the fan is guided to the convex side of the bulging part of the fan guide and is blown out from the exhaust port without flowing back into the machine. On the other hand, the muddy water attached to the rectifier such as the diode is removed from the fan guide. It flows down through the gap formed by the concave side of the bulge and drips from the exhaust port.
