摘要： PROBLEM TO BE SOLVED: To further improve the torsional rigidity and the bending rigidity of a joint portion between a female serration groove of an outer shaft and a male serration groove of an inner shaft. SOLUTION: A die 5 is pressed through one axial end side of a first drawn portion 21 of a fourth intermediate material 14, a second drawn portion 23 is formed on the outer peripheral face near one axial end side of the first drawn portion 21 with drawing work, and the outer diameter and the inner diameter of the first drawn portion 21 are shrunk. The male serration groove 71 of the inner shaft 7 is inserted into the female serration groove 4 of the outer shaft 2, and a retainer ring 8 is externally fitted to a lock recessed portion 22 in the state of elastically shrinking the diameter on one axial end side of the second drawn portion 23. In the state of assembling the inner shaft 7 on the outer shaft 2, the female serration groove 4 is strongly pushed against the outer periphery of the male serration groove 71 at two points of an inner diameter 231 on the other axial end side of the second drawn portion 23 and an inner diameter 232 on the one axial end side of the second drawn portion 23.

摘要： PROBLEM TO BE SOLVED: To provide an erroneous assembling prevention tool of a universal joint with small parts count, which can reduce manufacturing cost, and is low in insertion resistance when inserting a shaft into a connecting cylinder.SOLUTION: When inserting an external periphery surrounding part 71 of the erroneous assembling prevention tool 7 into the connecting cylinder 53 from the side of an edge 534 on the opposite arm side of the connecting cylinder 53, an internal periphery 711 is tightly fit to an external periphery 533, and thus the erroneous assembling prevention tool 7 is hardly fallen off from the connecting cylinder 53. When inserting the external periphery surrounding part 71 into the connecting cylinder 53, an R-recessed face 741 of the erroneous assembling prevention tool 7 abuts on an R-protruding face 535 of the connecting cylinder 53, and an axial position of the erroneous assembling prevention tool 7 is regulated. By press-inserting a first gripping claw 72 into an arm 52 on a side of a slit 56 from the side of the slit 56, and when engagement protrusions 722 reach the inside face 522 of the arm 52, the elastic deformation of the first gripping claw 72 is restored, an interval between the engagement protrusions 722 is narrowed, and an engagement face 724 is engaged with the inside face 522 of the arm 52.
摘要翻译：要解决的问题：提供具有小零件数量的万向节的错误组装防止工具，这可以降低制造成本，并且在将轴插入连接筒时具有低的插入阻力。解决方案：将错误组装防止工具7的外周围部分71从连接圆筒53的相对臂侧的边缘534的一侧插入连接圆筒53中时，内周边711紧密配合到外周533，因此错误组装防止工具7几乎不从连接筒53脱落。当将外周围的部分71插入连接筒53中时，错误组装防止工具的R形凹面741 7邻接连接圆筒53的R突出面535，并且限制错误组装防止工具7的轴向位置。通过从狭缝56的侧面将第一夹爪72压入狭缝56侧的臂52中，并且当接合突起722到达臂52的内表面522时，第一夹持的弹性变形爪72恢复，接合突起722之间的间隔变窄，并且接合面724与臂52的内表面522接合。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To stabilize an impact energy absorbing characteristic in a secondary collision, and to acquire sufficiently-long energy absorbing straight line part, even if a steering device is provided closer to an engine room etc.
SOLUTION: A driver collides with a steering wheel 12 in the secondary collision, and a locking projection 431 pulls a U-shaped portion 611 of an energy absorbing member 61 to a vehicle body front side. A first straight line 612 is pulled to the vehicle body front side, the vehicle body front side of a second straight line 614 is moved to a winding part 613 side to be wound on the outer periphery of a tilt center shaft 41, and the impact energy in the secondary collision is absorbed by plastic deformation when wound. The tilt center shaft 41 is journaled by resin bushes 42 to be easily rotated, and thereby the sliding of the energy absorbing member 61 when the second straight lines 614 are wound on the outer periphery of the tilt center shaft 41 can be reduced. As a result, the impact energy absorbing characteristic is stabilized.

摘要翻译：要解决的问题：为了稳定二次碰撞中的冲击能量吸收特性，并且获得足够长的能量吸收直线部分，即使转向装置设置得更靠近发动机室等。解决方案在二次碰撞中，驾驶员与方向盘12碰撞，锁定突起431将能量吸收构件61的U字状部分611拉向车身前侧。第一直线612被牵引到车身前侧，第二直线614的车身前侧移动到卷绕部613侧，卷绕在倾斜中心轴41的外周，并且冲击二次碰撞时的能量在伤口时被塑性变形所吸收。倾斜中心轴41由树脂衬套42支承以容易地旋转，从而可以减少当第二直线614缠绕在倾斜中心轴41的外周上时能量吸收构件61的滑动。结果，冲击能量吸收特性稳定。版权所有（C）2009，JPO＆INPIT
