  The present invention relates to a vehicular lamp, and more specifically, lamps each including a lamp unit having a light source and a light guide are arranged adjacent to each other in the vehicle width direction, and the lights from the respective lamps are provided. The present invention relates to a vehicular lamp in which each lamp has an optical sense of unity by light.

  Conventionally, as this type of vehicle lamp, for example, Patent Document 1 discloses a vehicle lamp having the configuration shown in FIG.

  That is, a first lamp unit 110 including a first light emitting element (not shown) and a first light guide 140 is incorporated in a lamp chamber formed by the first lamp body 120 and the first translucent cover 130. And a second lamp unit comprising a second light emitting element (not shown) and a second light guide 240 in a lamp chamber formed by the first lamp 100, the second lamp body 220 and the second light transmitting cover 230. The vehicular lamp 300 is constituted by the second lamp 200 in which 210 is incorporated, and the first lamp 100 and the second lamp 200 are attached adjacent to each other on the outer side in the vehicle width direction and on the inner side in the vehicle width direction, respectively. Yes.

  The inner leg 131 of the first translucent cover 130 and the outer leg 231 of the second translucent cover 230 are positioned adjacent to each other so as to be displaced inward in the vehicle width direction toward the rear of the lamp. It is extended to. The respective displacements include front regions 132 and 232 extending in the front-rear direction of the lamp, rear regions 133 and 233 extending in the front-rear direction of the lamp at an offset position inside the vehicle width direction with respect to the front regions 132 and 232, and the front region 132, It consists of three areas of intermediate areas 134 and 234 extending from 232 to the rear areas 133 and 233 toward the rear of the lamp and extending inwardly in the vehicle width direction.

  In the first lamp unit 110, the first light guide 140 extends in parallel to the vicinity of the first light-transmissive cover 130 toward the inner side in the vehicle width direction, and an end region 141 located on the inner side in the vehicle width direction has a rear part of the lamp. A tip end region 142 that is curved and extends to the side and further curved and located on the inner side in the vehicle width direction extends in parallel to the first light-transmitting cover 130 toward the inner side in the vehicle width direction. The tip end region 142 is located in the rear region 133 of the inner leg 131 of the first light transmitting cover 131. On the other hand, as for the 2nd lamp unit 210, the 2nd light guide 240 is extended in the vicinity of the 2nd translucent cover 230 toward the vehicle width direction outer side.

The reflected light is internally reflected (totally reflected) and emitted forward from the front surface.

  Accordingly, the vehicular lamp having the above-described configuration is 300, and when the first light emitting element of the first lamp 100 emits light (lights on), the light emitted from the first light emitting element passes through the first light guide 140 inside the vehicle width direction. The light is guided toward the tip end region 142 located at the position. At that time, most of the light emitted from the front surfaces of the end region 141 and the tip region 142 of the first light guide 140 is irradiated to the inner leg 131 of the first light-transmitting cover 130, and the inner leg 131. A part of the light that has passed through is further applied to the outer leg portion 231 of the second translucent cover 230.

  On the other hand, when the second light emitting element of the second lamp 200 emits light (lights up), the light emitted from the second light emitting element travels in the second light guide 240 toward the right end surface 244 located outside in the vehicle width direction. Light is guided. At that time, most of the light emitted from the right end surface 244 of the second light guide 240 is irradiated to the outer leg portion 231 of the second translucent cover 230, and a part of the light transmitted through the outer leg portion 231 is further increased. The light is applied to the inner leg 131 of the translucent cover 130.

  As a result, when the vehicle lamp 300 composed of the first lamp 100 and the second lamp 200 is viewed from the front, the inner leg of the first translucent cover 130 passes through the gap between the first lamp 100 and the second lamp 200. The portion 131 and the outer leg portion 231 of the second translucent cover 230 appear to shine. Therefore, the entire vehicular lamp 300 appears to shine continuously without the gap between the first lamp 100 and the second lamp 200 becoming a dark part.
