It changes in three types in the longitudinal direction). Moreover, as described above, these reflected images also change three-dimensionally.

  Furthermore, since the concave portion 62c in the high rotation region and the reflecting portion 61 between them are painted red, the reflected image between them is red. For this reason, the color tone (hue, lightness, saturation) of the reflected image also changes between a metallic tone (silver color) and red.

  As a result, the viewer can see the change in the shape of the reflected image and the three-dimensional change in addition to the change in color tone with more surprise and pleasure as an accent that shines brightly. Further, since the concave portions 62a, 62b, and 62c are provided as the scales 22 and 22a, the visibility can be improved and the driver who is the viewer can be alerted by the red reflected image.
