ABSTRACT:
An arrangement for a rotating vehicular mirror of the self-wiping type which is comprised of a circular mirror supported by means of a central shaft and driven by the vehicular slipstream by means of impellers distributed in the mirror circumference. The mirror construction includes an enclosed chamber mounted for rotation and at least part of one wall of the chamber being formed by the mirror element, the chamber defining a series of radially disposed closed passageways open at one end to the central region adjacent the axis of rotation and at the other end to a peripheral region adjacent the surface of rotation so that rotation of the chamber leads to circulation and recirculation of the enclosed air due to centrifugal force from the central region to the peripheral region and across the rear face of the mirror element.
