Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lighting tool for a vehicle being in a simple structure and being at low manufacturing costs. SOLUTION: The lighting tool for a vehicle has a lamp unit 4, a light-distribution pattern switching lens 19, and a lens position switching mechanism 20. The lamp unit 4 irradiates a light-distribution pattern P3 of a light-concentrating system. The light-distribution pattern switching lens 19 switches the light-distribution pattern P3 of the light-concentrating system irradiated from the lamp unit 4 to a light-distribution pattern P4 of a diffusion system. The lens position switching mechanism 20 switches the position of the light-distribution pattern switching lens 19 to a first position for making the light-distribution pattern P3 of the light-concentrating system pass through as it is and a second position for switching the light-distribution pattern P3 of the light-concentrating system to the light-distribution pattern P4 of the diffusion system.
