Abstract
The disclosure relates to a rotary indicating device adaptable to, for example, wheel covers for motor vehicles. The device includes a rotary base member having, on its front or rear surface, a plurality of indication regions which respectively consist of completely the same desired images and arranged at equal angular intervals about a rotary axis of the rotary base member. When the rotary base member rotates at more than a predetermined rotational speed, an observer located at a predetermined position with respect to the device can view a distinct constant image, appearing at a predetermined position of the rotary base member, due to the after image phenomenon.
