Description of the Related Art As shown in FIG. 5, a general spline joint used in a driving force transmission mechanism has a spline shaft member 1 and a spline hole member 2 splined together and provided on the spline shaft member 1. A circlip 4 having a circular cross section is fitted in the circumferential clip groove 3, and the outer peripheral portion of the circlip 4 is engaged with the end of the spline of the spline hole member 2.

を発生させる要因ともなる。更に、サークリップ４のへ
たりや摩耗により、初期の抜け力を保持できなくなる。That is, since the cross-sectional shape is circular and the cross-sectional area is small, the diameter reduction rigidity of the clip is low. Further, since the cross-sectional shape is circular, the contact portion between the spline hole member 2 or the spline shaft member 1 and the circlip 4 makes a line contact.
Since the spline shaft member 1 transmits torque and is repeatedly subjected to axial thrust force, the axial load is also applied to the circlip 4. A slight vibration of a machine such as a vehicle is added to this, and the backlash in the axial direction increases due to the fatigue and wear of the contact portion, which may cause a vibration problem in the machine such as a vehicle. Further, due to the fatigue and wear of the circlip 4, the initial pulling force cannot be maintained.
