PROBLEM TO BE SOLVED: To raise effectively visibility when a vehicular body banks in a head light of a motor cycle which comprises a lamp fitting unit for forming a light distribution pattern for a low beam and a left and right pair of auxiliary lamp fitting units each of that is for forming an auxiliary light distribution pattern that reinforces brightness of the light distribution pattern for a low beam when the vehicular body banks.SOLUTION: When a vehicular body banks left, an auxiliary light-emitting element 32R of a right side auxiliary lamp fitting unit 30R at a relatively high position is turned on, and, when the vehicular body banks right, an auxiliary light-emitting element 32L of a left side auxiliary lamp fitting unit 30L at a relatively high position is turned on. By means of this, even in a case that the vehicular body banks to any direction of the left and the right, an auxiliary light distribution pattern can be easily formed at an adequate position against a vehicular front-side road surface, to improve visibility.

    【課題】ロービーム用配光パターンを形成するための灯具ユニットと、車体がバンクしたときにロービーム用配光パターンの明るさを補強する補助配光パターンを形成するための左右1対の補助灯具ユニットとを備えた二輪車用前照灯において、車体がバンクしたときの視認性を効果的に高めるようにする。【解決手段】車体が左側にバンクしたときには、相対的に高い位置にある右側の補助灯具ユニット30Rの補助発光素子32Rを点灯させるとともに、車体が右側にバンクしたときには、相対的に高い位置にある左側の補助灯具ユニット30Lの補助発光素子32Lを点灯させる構成とする。これにより、車体が左右いずれの方向にバンクしたときであっても、車両前方路面に対して補助配光パターンを適正な位置に容易に形成可能とし、視認性向上を図る。【選択図】図1
