摘要： A shock absorbing type steering shaft comprising a tubular outer shaft having a female serration and a solid inner shaft having a male serration. After the outer diameter surface of the outer shaft is pressed inwardly in the radial direction to plastically deform an inner portion thereof, the inner shaft is inserted into the outer shaft so that the inner shaft is pressure-contacted and fixed to the plastically deformed portion of the outer shaft.

摘要： An elastic universal joint is constructed to prevent an interference between a front end surface of a shaft and a front edge of a second arm of a second yoke irrespective of an intersecting angle between two first and second yokes without increasing a size of the first yoke. For this purpose, a concave portion is formed in the front end surface of the shaft, and, in a state where the intersecting angle between the first and second yokes increases and a front edge of the second arm approaches closest to the front end surface thereof, this front edge enters the concave portion. A distance between a cross shaft and the front end surface is reduced corresponding to a depth of the concave portion, and the first yoke is downsized with a smaller weight, correspondingly.

摘要： In a method of manufacturing a shock absorbing type steering shaft, the fore end portion of a tubular outer shaft having a female serration formed on the inner peripheral surface thereof and the fore end portion of an inner shaft having a male serration formed on the outer peripheral surface thereof are brought into engagement with each other, and then the fore end portions of the two shafts are plastically deformed in the diametral direction thereof. Thereafter, the outer shaft and the inner shaft are displaced relative to each other toward each other in the axial direction thereof. The fore end portion of the small-diametered portion of the outer shaft is then pressure-fitted into the base end portion of the large-diametered portion of the inner shaft. At the same time, the fore end portion of the large-diametered portion is pressure-fitted into the base end portion of the small-diametered portion. Also, the intermediate portion of the small-diametered portion and the intermediate portion of the large-diametered portion are brought into loose engagement with each other.

摘要： In a collapsible steering shaft a collapse load is decreased while assuring the heat resistance of a coupling portion between an outer shaft and an inner shaft. In addition, a time during which a great collapse load is needed is also decreased. Female serration grooves on an inner surface of the outer shaft are engaged with male serration grooves on an outer surface of the inner shaft. A recess is formed on the outer surface of the inner shaft and is aligned with a root in the male serration grooves, and a steel ball is set in the recess. A part of this steel ball intrudes into a top part of a thread in the female serration grooves. A flat portion is formed by removing a part of the male serration grooves, whereby the top part crushed by the steel ball can be prevented from frictionally engaging with the male serration grooves.
摘要翻译：在可折叠的转向轴中，在确保外轴和内轴之间的联接部的耐热性的同时减小了塌陷负载。此外，还需要大塌陷负载的时间。在外轴的内表面上的母齿槽与内轴的外表面上的公齿槽啮合。在内轴的外表面上形成凹部，并且与雄齿锯齿槽中的根部对准，并且将钢球设置在凹部中。该钢球的一部分侵入到母齿槽中的螺纹的顶部。通过去除一部分雄性锯齿沟形成平坦部分，由此可以防止由钢球破碎的顶部与雄性锯齿槽摩擦接合。

摘要： In order to prevent a noise from being generated by the contact of a fixed meshing gear and an elevation meshing gear when a level of a steering wheel is adjusted, a fixed gear is fixed to an outer surface of a vertical plate of the fixed bracket, a lock plate is held by a hold member provided at a base of a leaf spring, and the engagement of the meshing gears is disengaged by a leg provided in the leaf spring. An inner surface of the vertical plate is always elastically urged toward the outer surface of the elevation bracket.
