Description

前記のボリューム逃がし手段、厚肉部の外周に設けられた周方向の1条もしくは複数条の溝よりなり、これにより前記締め付け時の余分なボリュームが前記溝の空間に逃がされ、締め付け力が全周に渡って均等化する。該溝は、より詳細には、肉厚の大きい部分ほど溝幅が大きく形成されていることが好ましく、あるいはまた、溝内部に凸条を有する断面略W字状に形成されていることが好ましい。 The volume relief means is thick portion Ri name than the grooves in the circumferential direction of the single-thread or plural rows provided on the outer peripheral surface of the extra volume when tightening the is released to the space of the groove Thus, The clamping force is equalized over the entire circumference. More specifically, it is preferable that the groove is formed to have a larger groove width as the thickness is larger, or alternatively, the groove is preferably formed in a substantially W-shaped cross section having a convex stripe inside the groove. .
