Zusammenfassung:	PROBLEM TO BE SOLVED: To enable a reflector 1 to be rotated against a lamp housing 2 with a horizontal line LH1 including a ball joint 3 as a center by a simple method, even in case an aiming screw 5 is arranged, at a position away from the horizontal line LH1 including the ball joint 3 and at the position away from a horizontal line LH2 including an aiming screw 4. SOLUTION: In the aiming device of a lighting fixture for a vehicle connecting a reflector 1 and a lamp housing 2 through a ball joint 3 and two aiming screws 4, 5, a pitch P2 of a male screw part 5a of the aiming screw 5 is set at a product (P1×(L2/L1)) of a pitch P1 of a male screw part 4a of the aiming screw 4 and a ratio (L2/L1) of a distance L2 from the horizontal line LH1 to the aiming screw 5 to that L1 from the horizontal line LH1 to the aiming screw 4.
