PROBLEM TO BE SOLVED: To suppress a change quantity of the clearance between a recessed shape notch formed to a carrier bracket and the outer peripheral face of a turning arm receiving therein even in adjusting an angle position of the carrier bracket clamped by a welding jig. SOLUTION: A first clamp support device 42 supporting a carrier clamp device 32 is provided with a first guide device 82 to guide a carrier clamp device 32 clamping a carrier bracket 10 along the circular arc around the axial center of a turning arm 14 and a first positioning device 90 to position the carrier clamp device 32 guided by the first guide device 82 so that the carrier bracket 10 clamped thereby is moved to a prescribed first angle position corresponding to a camber angle, changing of the first angle position is performed along the circular arc around the axial center of the turning arm 14, the clearance K between a recessed shape notch 26 formed to the carrier bracket 10 and the outer peripheral face of the turning arm 14 received therein is reduced, variance in welding conditions or welding quality is appropriately suppressed.
