欠点を有する。The object of the present invention is to complete the installation by simply drilling a hole in the mating member to which the fulcrum part of the link member is to be attached, tapping a female thread into the hole, and screwing the male thread of the ball receiving part into the female thread. A method for manufacturing a universal ball joint in which a male thread is formed on the outer periphery of the ball receiving part.More specifically, the same inventor as the present application set the ball in a mold like a core, casts a die-cast molten bearing alloy, and casts it in one piece. It is known to form a gap between the pole and the ball receiver by placing the ball receiver on a stand or the like and evenly hitting the outer periphery of the ball receiver.
(Refer to Publication No. 6) The outer periphery of the ball receiving part of the universal ball joint of the present invention is not formed by tapping to form a gap, but by thread rolling on the outer periphery of the ball receiving part to form a thread. The object of the present invention is to provide a new method for manufacturing a swivel ball joint that focuses on the resulting expansion, that is, the extension in the axial and radial directions. In addition, the above-mentioned special public service
The ball joint described in 0I No. 6 is known as a tension type ball joint in the middle of the link mechanism, and the outer rod of the ball joint can rotate back and forth or left and right around the sphere. Simultaneous left and right rotation has the disadvantage that it can only be rotated within a very small range.

角度範囲を示す。After casting, the universal ball joint is taken out from the molds 5 and 6, first, the hot water burr formed on the ball receiving part 7 is removed, and then a male thread 8 is formed on the outer periphery of the ball receiving part 7 by thread rolling. Form. Since the inner circumferential surface of the die-cast bearing alloy due to the pressure of thread rolling extends in the axial and radial directions, a gap is formed between the outer circumferential surface of the ball 2 and the inner circumferential surface of the pawl receiving part 7. In the drawing, reference numeral 14 is a link member that is screwed into the screw 4 of the stud 1, 15 is a grease hole formed in the ball receiving part 7, 16 is a nut for attaching a spanner formed in the stud, and 17 is a spanner for the ball receiving part. The hanging nut, 8' indicates the angle range in which the ball stud can swing within the ball receiving part.
