To achieve both light distribution characteristic and designability of a vertical line light emitting type direction indicator lamp.SOLUTION: A vehicular direction indicator lamp 10 which includes a vertical type light emission surface includes a tabular light guide body 100 which is disposed so that one plate surface opposes to a light emitting element and one end surface opposes to the light emission surface, and which guides the light emitted from the light emitting element to the light emission surface. The light guide body 100 includes: a light incident part provided on one plate surface of the light guide body 100; a first reflection part 105 provided on the other plate surface 100B of the light guide body 100, and including a conical reflection surface; and a second reflection surface 106 provided on the other end surface of the light guide body 100, and including a circular arc-shaped reflection surface; and a light emission part 102 provided at the one end surface of the light guide body 100, and for emitting light toward the light emission surface. The light emission part 102 includes: a first emission surface 102A provided so as to extend in the vehicular vertical direction and for emitting light toward a vehicular rear side; and a second emission surface 102B provided so as to extend in the vehicular vertical direction and for emitting light toward vehicular lateral side.SELECTED DRAWING: Figure 5
【課題】縦ライン発光タイプの方向指示灯の配光特性と意匠性とを両立させる。【解決手段】縦型の光出射面を備える車両用方向指示灯10は、一方の板面が発光素子と対向し、一端面が光出射面と対向するように配され、発光素子から発せられた光を光出射面に導く板状の導光体100を備える。導光体100は、導光体100の一方の板面に設けられた光入射部と、導光体100の他方の板面100Bに設けられた円錐状の反射面を備える第1反射部105と、導光体100の他端面に設けられ円弧状の反射面を備える第2反射部106と、導光体100の一端面に設けられ光出射面に向けて光を出射させる光出射部102とを備える。光出射部102は、車両上下方向に延びるように設けられ車両後方に向けて光を出射させる第1出射面102Aと、車両上下方向に延びるように設けられ車両側方に向けて光を出射させる第2出射面102Bとを備える。【選択図】図5
