PROBLEM TO BE SOLVED: To provide a ball joint which inexpensively secures conductivity between a ball stud and a housing without affecting the slidability and the reliability.SOLUTION: A part of a conductor 51 which is electrically connected with a conductive housing 16 is disposed at a through hole 46 which communicates with a sliding surface 47 of an insulative ball seat 17. The conductor 51 is placed in pressure contact with a ball part 21 by a coil spring 52 disposed at a communication hole 34 of the housing 16. While the slidability of the ball part 21 is secured by the sliding surface 47 of the ball seat 17, conductivity is inexpensively secured between a ball stud 15 and the housing 16 by the conductor 51. |
