2. 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.

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.

Therefore, an object of the present invention is to increase the cross-sectional area of the circlip and to expand the contact area of the circlip with both the spline hole member and the shaft member to reduce the surface pressure at the contact portion.
