Abstract
The object of the invention is to prevent the quantity of airflow by a fan from decreasing in dependence on the distance between the fan and obstacles such as an engine in a device for introducing and discharging cooling air having a shroud with a high covering rate. In the device for introducing and discharging cooling air having the shroud with the high covering rate, an airflow direction changing member is provided downstream of the fan, and each fixed blade of the member has a shift angle in the radial direction and an attack angle in a rotation direction of the fan, so that the air tends to be discharged outward in the radial direction.
