Abstract
A light shielding part includes a slit provided between a first light guide body and a second light guide body, and an attenuation part which has unevenness formed by print and is additionally provided near end sides of the first light guide body and the second light guide body. The light shielding part can prevent light from being transmitted between the first light guide body and the second light guide body. With this configuration, when illumination parts of the first and second light guide bodies are illuminated, it is possible to illuminate the illumination parts of the first and second light guide bodies at different timings without the illumination part of one light guide body being illuminated with light leaked from the other light guide body.
