摘要： In the damper device, when the large diameter portion (51) does not apply an impact force on the flange portion (532), the elastic body (53b, 63b, 73b) is disposed in one of the housing (22) and the cylindrical portion with a gap and when the large diameter portion applies the impact force on the flange portion, the elastic body is compressed by the restricting surface and the flange portion in an axial direction to be deformed into a state that the elastic body is brought into contact with all of the housing, the restricting surface (52b, 62b), the cylindrical portion (531) and the flange portion to be filled in the gap. The impact receiving member (53a) is restricted from a movement relative to the housing by the deformed elastic body when the end portion (531 c) of the cylindrical portion (531) is advanced into the relief portion (52f, 62f, 72f) and the impact receiving member keeps a non-contact state with the housing.
摘要翻译：在阻尼装置中，当大直径部分（51）不对凸缘部分（532）施加冲击力时，弹性体（53b，63b，73b）设置在壳体（22）和圆柱形并且当大直径部分对凸缘部分施加冲击力时，弹性体被限制表面和凸缘部分在轴向方向上压缩，从而变形成弹性体接触的状态与所有的壳体，限制表面（52b，62b），圆柱形部分（531）和凸缘部分填充在间隙中。当圆筒形部分（531）的端部（531c）前进到释放部分（52f，62f，72f）中时，冲击接收部件（53a）受到由变形的弹性体相对于外壳的移动的限制，冲击接收构件保持与壳体的非接触状态。

摘要： A steering system is provided in which smooth operation of a ball screw mechanism can be maintained and a driven pulley and a ball screw nut can be coaxially aligned accurately. The driven pulley (44) is disposed around an outer periphery of a rack shaft (12) coaxially therewith, and is fitted onto the ball screw nut (51) so as to be integrally rotatable with an aligning structure (48) interposed therebetween. The aligning structure (48) includes locking grooves (61) formed on an inner peripheral surface of the driven pulley (44), mounting grooves (62) formed on an outer peripheral surface of the ball screw nut (51) and radially opposed to the respective locking grooves (61), and elastic members (63). Each elastic member (63) has a pair of base parts (63a, 63b) and a spring part (63c) integrally formed between the base parts (63a, 63b), is disposed in the corresponding mounting groove (62) with the base parts (63a, 63b) spaced apart from circumferential side surfaces (62b, 62c), and is disposed between the mounting groove (62) and the corresponding locking groove (61) such that the spring part (63c) is locked on inner surfaces (61a, 61b) of the locking groove (61) in a radially compressed manner.

摘要： A steering system includes a rack housing 17 in which a rack shaft 12 is housed, rack ends 14 fitted to respective end portions of the rack shaft 12 and coupled to respective steered wheels 16, and shock-absorbing members 70 provided between the rack housing 17 and the respective rack ends 14. When the rack shaft 12 moves in a direction in which an end face 63 of the rack end 14 approaches a restricting surface 17d of the rack housing 17 and thus the rack shaft 12 reaches a position L2 after the shock-absorbing member 70 is compressed by a compression amount Dl, a control unit creates a normal input end through electronic stopper control of reducing an assisting force to be generated by a motor. This restricts movement of the rack shaft 12 in a direction in which the end face 63 approaches the restricting surface 17d.
