Document Type and Number:
WIPO Patent Application WO/2018/181010
Kind Code:
A1
Abstract:
Provided is a ball joint manufacturing method for manufacturing a ball joint equipped with: a ball stud that includes a substantially spherical metal ball part; and a resin housing in which the ball part of the ball stud is accommodated so as to be able to rotate. The ball joint manufacturing method comprises: a step for forming the housing so as to cover the outer periphery of the ball part; an induction heating step for subjecting the ball part to induction heating in a state where the ball part is accommodated in an accommodating part of the housing until a prescribed target temperature is reached; and a cooling step for cooling the ball part after the induction heating. A torque adjustment step, which includes the induction heating step and the cooling step, is repeatedly performed.
