ABSTRACT:
The disclosure relates to a rotary indicating device preferably in use, for example, for wheel covers for motor vehicles. The device includes a base member adapted to be rotated about a rotary axis and having an indication region thereon. The indication region indicates a desired image and comprises a plurality of reflection faces. The reflection faces are inclined in the same direction and also at the same angle with respect to a standard plane perpendicular to a rotary axis of the rotary base member. Thus, when the base member rotates, the observer can visually recognize the image as a clear single image due to the after image phenomenon.
