Abstract
A scuff plate of the invention is a scuff plate which has a luminous unit of which a side surface of side surfaces forms a luminous surface, a light source unit which emits light to the luminous unit, and a light guiding unit which is disposed in such a manner that a side surface thereof faces the luminous surface, wherein the light guiding unit has a luminous surface portion which expands in an intersecting direction relative to a front surface thereof. The scuff plate of the invention provides a scuff plate which has superior design properties without increasing the thickness of the whole thereof.
