摘要： A small gap is formed between a worm shaft 3 and a second bearing 20, so that the worm shaft can be tilted relative to the inner ring 20a of the second bearing 20 without fail when preloaded by a torsion spring 14. An elastic member 41 is provided in at least portion of a circumferential groove 40 in the small gap. The worm shaft 3 and the inner ring 20a of the second bearing 20 are not in contact with each other, and their metallic clank in the small gap can be prevented. By providing a projecting portion(s) 3b on one side or both sides, with respect to the axial direction, of the circumferential groove 40, the small gap between the worm shaft 3 and the inner ring 20a of the second bearing 20 can be made large, and it is possible to enlarge the range over which the worm shaft 3 can swing.

摘要： The present invention provides construction that keeps the load required for a locking capsule 50d that is supported by the steering column to come out in the forward direction from a locking hole 48b that is formed in a fastening bracket 11e on the vehicle side low. Small through holes 52e are formed in a flange section 51d of the locking capsule 50d. Small notch sections 62a that are each open toward the inside of the locking hole 48b are formed in portions of the fastening bracket 11e on the vehicle side around the locking hole 48b that are aligned with each of the small through holes 52e. Injection molding is performed to inject synthetic resin 72 such that the synthetic resin 72 spans between these small through holes 48b and small notch sections 62a, and connects the locking capsule 50d and the fastening bracket 11e on the vehicle side. Moreover, part of the synthetic resin 72 penetrates into and solidifies in a small space 71 between the inside surfaces of the locking hole 48b and the outside surfaces of the locking capsule 50d.

摘要： A torsion coil spring 30 applies an elastic force to a worm shaft 29 in a direction towards a worm wheel, via a pre-load pad 70. The pre-load pad 70 restricts displacement in relation to the widthwise direction, by one side face portion of a holder 61 fixed to a gear housing 22. Due to the elastic deformation of the pre-load pad 70 itself based on the elastic force of the torsion coil spring 30, the side face of the pre-load pad 70 is abutted against the one side face portion of the holder 61, so that a gap between the pre-load pad 70 and the one side face portion is minimized. As a result, the occurrence of a teeth fitting noise in the worm reduction gear 16 is suppressed.
摘要翻译：扭力螺旋弹簧30经由预加载垫70向蜗轮轴29朝向蜗轮的方向施加弹性力。预加载垫70通过固定在齿轮箱22上的保持架61的一个侧面部来限制相对于宽度方向的位移。由于预压垫70自身基于扭力螺旋弹簧30的弹力而弹性变形，所以预加载垫70的侧面与支架61的一个侧面部抵接，预加载垫70和一个侧面部之间的间隙最小化。结果，抑制了蜗轮减速装置16中的齿配合噪声的发生。
