用いて抱締め固定をしている。In the front axle a 2 of FIG. 11, after tightening the bearing e, e, color f, g, h screwed a cylindrical nut l the threaded portion d, as with the large diameter portion b cylinder The nut 1 is held and fixed using the seat m.
(考案が解決しようとする課題) 各従来例において、前車軸a1、a2の大径部bは、フロ
ントフォークBに直接抱締め固定されるため強固に固定
されるが、他端dではこのような固定手段は用いられて
はいない。即ち第9図の軸a1では一端がねじ部dと固定
部iのねじ結合であるため、結合力が抱締め固定部に比
して低く、前車軸a1に加わる回転トルクに対する抵抗や
結合部の剛性が低い。(Problems to be Solved by the Invention) In each conventional example, the large diameter portions b of the front axles a 1 and a 2 are firmly fixed because they are directly hugged and fixed to the front fork B. No such securing means is used. That is, since one end in the axial a 1 of FIG. 9 is a screw connection of the fixing portion i and the threaded portion d, lower than the fixing unit coupling force hug, resistance and binding to the rotational torque before applied to the axle a 1 The rigidity of the part is low.
また第11図の前車軸a2は、受座mにおいて抱締め固定
されるが、この固定構造は、筒状ナットlを介して間接
的に前車軸a2を固定するものであるため、結合力は大径
部b側の結合部に比べれば低い。Further, the front axle a 2 in FIG. 11 is fixedly fastened at the seat m. However, since this fixing structure indirectly fixes the front axle a 2 via the cylindrical nut l, The force is lower than the coupling portion on the large diameter portion b side.
したがって本考案は、小径部c側においても大径部b
側と同じ結合力をもつ固定構造を得ることを課題とす
る。Therefore, the present invention is applicable to the large-diameter portion b on the small-diameter portion c side.
It is an object to obtain a fixing structure having the same coupling force as the side.
