PROBLEM TO BE SOLVED: To widen a contact area in a connection structure of a universal joint yoke and a shaft.SOLUTION: A first yoke 12 (universal joint yoke) includes a cylindrical coupling part 40 into which an end part 3a of a steering shaft 3 is inserted. In a second circumferential region 42 of the coupling 40, a slit 43 extending in an axial direction X is formed. The second circumferential region 42 contains a flexural deformation part 44 flexurally deforming around a support part SP with fastening of a fastening bolt 20 (fastening shaft). The support part SP is arranged on a slit 43 side with respect to a non-fitting region 32 of the steering shaft 3. With flexural deformation of the flexural deformation part 44, a pressing energization part 45 arranged in the flexural deformation part 44 is configured to press and energize the non-fitting region 32 of the steering shaft 3 toward an opposite side of the slit 43.SELECTED DRAWING: Figure 4
【課題】自在継手ヨークとシャフトの連結構造において接触面積を広くする。【解決手段】第1ヨーク12(自在継手ヨーク)が、ステアリングシャフト3の端部3aが挿入された筒状の連結部40を備える。連結部40の第2周方向領域42に、軸方向Xに延びるスリット43が形成される。第2周方向領域42は、締付ボルト20(締付軸)の締付に伴って、支点部SPの回りに曲げ変形する曲げ変形部44を含む。支点部SPは、ステアリングシャフト3の非嵌合領域32よりもスリット43側に配置される。曲げ変形部44の曲げ変形に伴って、曲げ変形部44に配置された押圧付勢部45が、ステアリングシャフト3の非嵌合領域32をスリット43の反対側へ向けて押圧付勢する。【選択図】図4
