Abstract
An electric motor driven fan particularly for use on motor vehicles where water may be splashed into and onto the fan motor, includes a labyrinth-like seal in which a pair of concentric rings are formed on an integral with the fan hub and extend toward the drive motor defining an annular space therebetween, and the motor mounting bracket is provided with a non-rotating ring concentric to the pair of rings on the hub and extending from the bracket into the annular space, thereby preventing direct splash in or straight line intrusion of water into the space between the motor housing and the hub.
