Abstract
Abstract The decorative part of this invention, which means a part having an aesthetically treated indication, comprises a first indicator which permits the transmission of light, a semitransparent part placed behind the first indicator which reflects the light coming from the front and passes the light coming from the rear, a second indicator which permits the partial transmission of light and is placed behind the semitransparent part, and an illuminant placed behind the second indicator. Thus, it is possible to switch the display of the decorative part as desired by turning on and off the illuminant at proper time.
