Abstract
Provided is a display unit that incorporates a dial, a central display device, and an indicating needle. The indicating needle includes a substrate provided beneath the display device, a light source on a surface of an end of the substrate; and a light guide. The light guide includes a first light-guide portion extending vertically with its lower end facing the light source of the substrate, a second light-guide portion extending horizontally from the first light-guide portion, a third light-guide portion extending vertically from the second light-guide portion, and a needle portion extending horizontally such that the dial is pointed to by the end of the needle portion. The display unit may include a light-guide cover that prevents leakage of light and a regulation portion that restricts undesirable movement of a lead wire which might obstruct with rotation of the indicating needle.
