PURPOSE: To improve reliability in actuation by providing an inwall part with a taper provided outward separated from an opening end part of a socket member on the socket member. CONSTITUTION: An upper part side wall part 50 and a cylindrical side wall part 52 roughly curved to form an upper part window region of a ball joint 10 and a cylindrical side wall part 54 with a taper provided outward are provided on a socket member 12. Consequently, as it is possible to materially prevent escape of a ball stud 14, reliability in actuation is improved. |
