PROBLEM TO BE SOLVED: To provide a ball joint link attaining reductions in weight, cost and torque while securing rigidity and strength. SOLUTION: A ball part 41 and a ball seat 17 are assembled to a socket 16. An arm part 12 is then welded in a position where the spherical center of the ball part 41 coincides with an axis C2, on the outer peripheral surface of the socket 16. Since a thinner and hollow member can be used as the arm part 12, the weight can be reduced while securing rigidity and strength. The cost can be reduced because of not requiring a complicated manufacturing process, and torque can be reduced because a bearing pressure to the ball part 41 of the ball seat 17 can be reduced by the welding heat of the arm part 12.
