摘要： A vehicular lamp including a light guide in which light emitted from a light-emitting diode (30) is incident into a relatively short light guide (20), which extends in a horizontal direction intersecting the front-back direction of the lamp, from a left end surface (20a) and thereafter totally reflected by a plurality of reflective elements (20s) provided in the rear surface portion (20c) and then emitted out from the front surface portion (20d) toward the front of the lamp. A first incident portion (20a1) is provided in an intermediate region, in the front-back direction, of the left end surface (20a) of the light guide (20) so as to cause the light emitted from the light-emitting diode (30) to be incident into the light guide (20) while being refracted toward the rear of the lamp.

摘要： Disclosed is a vehicular lamp with a light guide that extends along a curve which becomes a convexed shape forwardly. A first area of the light guide positioned on an inner peripheral side of the curve is configured by a plane that extends in a direction inclined toward a left end surface side with respect to a second area other than first area. As a result, light which is incident on the light guide from the first area to which light from an LED is emitted is largely refracted forwardly to prevent the light from directly reaching a reflection element positioned in the vicinity of the right end surface. In addition, point light is prevented from being generated as the light totally reflected by the reflection element is extremely brighter than the light that is totally reflected by another reflection element as in the related art.
