摘要： A stop mechanism (23) of a helm device (16) includes a rotation member (80) which can be relatively rotated with respect to a steering shaft (22), rotatable disks (81), fixed disks (82) opposed to the rotatable disks (81), and an electromagnet (83) which presses these disks (81, 82) against one another. An inversion control pin (110) is provided in the steering shaft (22). Slits (120) are formed in a cylindrical portion (80a). Both ends of the inversion control pin (110) are inserted into the slits (120). The slits (120) are shaped to be elongated in a circumferential direction of the cylindrical portion (80a). A first pin receiving stopper wall (121) is formed on one end of the slits (120). A second pin receiving stopper wall (122) is formed on the other end of the slits (120). The inversion control pin (110) can move within the range of inversion allowance angle (θ) between the pin receiving stopper walls (121, 122).

摘要： A hollow coil spring and a method for manufacturing therefor can prevent corrosion at an inner surface and can improve product appearance. In an end sealing step, an end Wa is sealed by which the core material of the end Wa of a spring member W is gathered by machining. It is preferable that spinning be carried out as a machining. For example, a squeezing roller R is moved in an axial direction as necessary, while the end of the spring member W is pressed to the inside in a radial direction by the squeezing roller R. As a result, the end Wa of the spring member W is sealed as shown in Fig. 3 , and therefore, it is not necessary to use another member such as a lid member. For example, the end sealing step can be immediately carried out after an inner surface processing step. In a coil forming step after the end sealing step, formation of clearance can be prevented at the end Wa, even if the end Wa of the spring member W is gripped and the spring member W is wound around the rod.

摘要： The present invention provides a hollow seamless pipe for high-strength springs, in which the occurrence of decarburization in an inner peripheral surface and outer peripheral surface is reduced as much as possible, surface layer parts can be sufficiently hardened in the outer peripheral surface and the inner peripheral surface in a quenching step at the time of spring production, and sufficient fatigue strength can be secured in springs to be formed. The present invention relates to a hollow seamless pipe for a high-strength spring, which is composed of a steel material comprising 0.2 to 0.7 mass% of C, 0.5 to 3 mass% of Si, 0.1 to 2 mass% of Mn, more than 0 mass% and 0.1 mass% or less of Al, more than 0 mass% and 0.02 mass% or less of P, more than 0 mass% and 0.02 mass% or less of S, and more than 0 mass% and 0.02 mass% or less of N, wherein the C content in an inner peripheral surface and outer peripheral surface of the hollow seamless pipe is 0.10 mass% or more, and a thickness of a whole decarburized layer in each of the inner peripheral surface and the outer peripheral surface is 200 µm or less.

摘要： A disc spring and a production method therefor are provided in which an attempt is made to improve precision of an inside diameter portion, and in which residual stress can be applied to an inside diameter portion side edge of a tensile surface. Shot peening is carried out at at least a tensile surface 114A, after a chamfered portion 121A is formed at an inside diameter portion 112A side edge of a tensile surface 114A in a blank 100A. Residual stress is applied to the chamfered portion 121A of the inside diameter portion 112A side edge of the tensile surface 114A. The inside diameter portion 112A is machined after the shot peening. In this case, since at least an outside diameter portion side of the chamfered portion 121A remains, the remaining chamfered portion 121A constitutes the inside diameter portion 112A side edge of the tensile surface 114A after the machining. Therefore, the inside diameter portion 112 side edge of the tensile surface 114 in which the maximum stress can be generated in the disc spring 100 has residual stress.
摘要翻译：提供一种碟形弹簧及其制造方法，其中试图提高内径部分的精度，并且可以对拉伸表面的内径部分侧边缘施加残余应力。在坯料100A的拉伸面114A的内径部112A侧边缘形成有倒角部121A后，至少在拉伸面114A上进行喷丸硬化处理。残余应力被施加到拉伸表面114A的内径部分112A侧边缘的倒角部分121A。在喷丸硬化后加工内径部分112A。在这种情况下，由于倒角部121A的至少外径部侧保留，所以余下的倒角部121A构成加工后的拉伸面114A的内径部112A的侧缘。因此，盘簧100中可能产生最大应力的拉伸面114的内径部112侧边缘具有残余应力。

摘要： Provided is a boot band 31 that is capable of preventing the occurrence of buckling in the inner-layer portion of a band body 33. In the boot band 31, by applying a diameter-reducing tightening force on the band body 33 when an engagement pawl 41 of the inner-layer portion 35 of the band body 33 has entered a top-end engagement hole 42 of the outer-layer portion 34 of the band body 33, the top-end engagement hole 42 rides over the engagement pawl 41. Buckling is prevented by providing, at the area of the top-end engagement hole 42 opposite where the engagement pawl 41 enters therein, a guide means 51 that faces the engagement pawl 41.
