Abstract
A linear light guide or light guides disposed in a lamp chamber have a light guide neighboring region, in which the portions close to light incidence end portions are close to each other, and a light-emitting portion or portions are disposed so as to be offset from a luminous region of a light source unit and to have portions that extend from the light guide neighboring region and separate from each other. A translucent diffusion cover that covers the light guide neighboring region is provided at least in front of the light guide neighboring region. Part of the light from the light guide neighboring region is diffused by the diffusion cover and then emitted through the diffusion cover, so that light emitted through the light-emitting portion and the diffusion cover is continuous, so that it appears as if the light guide that is continuous is emitting light.
