The ball part 42 is rotatably supported by the socket part 31 through a resin member 50. A noise generating part (protruding part 80) held by the socket part 31 is brought into contact with the ball part 42 and generates noise by metal contact before a part of the resin member 50 is worn.SELECTED DRAWING: Figure 3 |
