    摘要： A reduction gear is provided. The reduction gear includes: a worm made of a metal; and a worm wheel having gear teeth engaged with the worm, wherein at least the gear teeth of the worm wheel are made of a synthetic resin containing reinforcing fibers, and wherein an engagement surface of the gear teeth is so processed that a containing ratio of the reinforcing fibers of a surface layer is lower than that of the reinforcing fiber of an inner portion. By improving initial acquaintanceship of the engagement surface of the teeth gear of the worm wheel, it is possible to increase a durability-allowable transmission tongue. In addition, by reducing a friction of the worm, it is possible to provide a reduction gear with the worm having a lengthened lifetime.

    摘要： An electric power steering apparatus can maintain suitable backlash in a temperature changing atmosphere even if a gear consisting of a metallic cylindrical core portion and a toothed resin outer ring portion. The thickness of the resin outer ring portion is suitably determined by the coefficients of linear thermal expansion of a driving gear, a driven gear, a housing, the addendum of the driven gear and the center distance between the driving gear and the driven gear. Even if the temperature of the atmosphere changes, the positional relation between the gears is unchanged. Thus, the backlash is substantially unaltered.

    摘要翻译： 即使由金属圆筒形芯部和齿形树脂外圈部组成的齿轮，电动助力转向装置也能够在变温气氛中保持适当的间隙。 树脂外圈部分的厚度适当地由驱动齿轮，从动齿轮，壳体，从动齿轮的齿顶和驱动齿轮与从动齿轮之间的中心距离的线性热膨胀系数决定。 即使大气的温度变化，齿轮的位置关系也不变。 因此，齿隙基本上没有变化。
