PROBLEM TO BE SOLVED: To provide a vehicular blower improving cooling efficiency. SOLUTION: The vehicular blower includes a blower motor for driving an impeller, a fan case 33 storing the impeller and having cooling air inlet and outlet, and a separation duct 36 mounted on the outside of the fan case 33 and arranged in communication with the cooling air outlet to the inlet. Outside air taken from the outside of the fan case 33 is discharged into the separation duct 36 so as to be separated into first cooling air including much dust and second cooling air including less dust than the first cooling air using the centrifuging operation of the impeller. The first cooling air is discharged as cooling air for the blower motor from the cooling air inlet 33b via the first duct 37 of the separation duct 36, while the second cooling air is discharged as cooling air for cooled equipment therefrom via a second duct 38 of the separation duct 36.
