The cam portion 20b incorporated in the pivot fitting 20a has a lower cam cylinder 23 on the inner side and a small diameter cylinder 23b.
In addition, since the outer cam surfaces 22f and 23f of the cam cylinders 22 and 23 and the inner cam surfaces 22g and 23g are cam-coupled to each other, the upper cam cylinder 22 is connected to the lower cam cylinder 23. It slides up and down along the outer peripheral surface 23e of the small diameter cylinder 23b. When the upper cam barrel 22 slides up and down, the cam barrels 23 and 22 vibrate due to the rotation between the lower cam barrel 23 and the upper cam barrel 22 in the pivot fitting 20a. When this vibration is large, a sound is generated by the rotation between the lower cam cylinder 23 and the upper cam cylinder 22.
