Abstract

Le problème à résoudre dans le cadre de la présente invention est de proposer une structure de fixation qui soit conçue pour que la facilité de montage d'une partie de fixation de corps d'arbre à un corps d'arbre principal soit suffisamment améliorée. La solution proposée consiste en une structure de fixation qui est conçue de manière telle qu'une surface inclinée d'extrémité avant soit formée à l'extrémité avant d'un corps d'arbre principal afin de croiser obliquement l'axe du corps d'arbre principal. Ceci élimine la nécessité d'aligner un trou de fixation et le corps d'arbre principal l'un avec l'autre avant de commencer le travail de fixation, et l'extrémité la plus en avant du corps d'arbre principal peut facilement passer à travers le trou de fixation en faisant correspondre seulement approximativement les positions de l'extrémité la plus en avant du corps d'arbre principal et du trou de fixation. Une fois que l'extrémité la plus en avant du corps d'arbre principal a été insérée dans le trou de fixation, le bord de la surface inclinée d'extrémité avant du corps d'arbre principal ne prend pas appui contre le bord du trou de fixation au cours du travail de fixation suivant. En conséquence de cette configuration, le travail n'est pas entravé, et la facilité de monter la partie de fixation de corps d'arbre sur le corps d'arbre principal est suffisamment améliorée.
