BALL BEARING

The inner circumference of a second rivet hole (12b) in the present invention is formed from a sheared surface (17b) with a constant cylindrical shape in which the inner diameter does not change along the axial direction and a fracture surface (18b) with a tapered shape that gradually expands in dia...

Beschreibung
Zusammenfassung:	The inner circumference of a second rivet hole (12b) in the present invention is formed from a sheared surface (17b) with a constant cylindrical shape in which the inner diameter does not change along the axial direction and a fracture surface (18b) with a tapered shape that gradually expands in diameter from the sheared surface (17b) toward a mating surface (16b). La circonférence interne d'un second trou de rivet (12b) dans la présente invention est formée à partir d'une surface cisaillée (17b) ayant une forme cylindrique constante dans laquelle le diamètre interne ne change pas le long de la direction axiale et une surface de fracture (18b) ayant une forme effilée qui s'étend progressivement en diamètre à partir de la surface cisaillée (17b) vers une surface d'accouplement (16b). 第２鋲穴（１２ｂ）の内周が、軸方向に沿って内径が変化せず一定の円筒状のせん断面（１７ｂ）と、せん断面（１７ｂ）から合わせ面（１６ｂ）に向かって次第に拡径するテーパ状の破断面（１８ｂ）とで構成されている。
