The invention provides a saddle riding type vehicle equipped with a light bulb illuminator, which is changed more easily without damages of appearance quality and water resistance of an illuminator. The reflector part (44) emitting light of the reflected light bulb (60) has a concave part (44a), which depresses to the reversed direction of the direction of the illumination. The lens (42) has a concave part (42a) depressed toward to the pullout direction (D1) and matched with the reflector part (44) capable of being pulled out along the irradiation direction, when the lens (42) is mounted on the reflector part (44), the concave part (42a) is overlapped with the concave part (44a). Then lens (42) is able to be pulled out, until the light bulb (60) formed between the concave part (44a) and the concave part (42a) can pass an opening part (40a).
