摘要： Both ends of a screw shaft 35 are supported on a vehicle body side bracket 19 so that only rotation is allowed. The screw shaft 35 is rotated by an electric motor 28. A nut member 44 is threadedly engaged with an intermediate portion of the screw shaft 35. The nut member 44 is held on inside of a nut holder 43. The nut holder 43 and nut member 44 are allowed to be shifted each other in longitudinal direction of the nut holder 43 which is perpendicular to both the shaft portion extending parallel to oscillation center axis of a steering column 4a and the axial direction of the screw shaft 35. The nut holder 43 is supported on the steering column 4a so as to be rotated about the shaft portion of the nut holder 43 relative to the steering column 4a.

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： An electric power steering apparatus capable of outputting an auxiliary steering force by an electric motor, includes a support device (20) supporting a rack shaft (10). The rack shaft (10) has support device guide surfaces, i.e., rolling surfaces (10b, 10b) extending in a longitudinal direction in at least two portions on an outer peripheral surface. The support device (20) has cylindrical rollers (23) rolling on the rolling surfaces (10b, 10b) in directions intersecting each other while pressing the rolling surfaces in a case where the rack shaft (10) is viewed in the longitudinal direction. Therefore, the rack shaft (10) can be supported by the cylindrical rollers (23) with a low friction, and the rolling surfaces (10b, 10b) provided on the outer peripheral surface of the rack shaft (10) are pressed by the cylindrical rollers (23), whereby the rack shaft (10) can be supported from two different directions. Hence, an axis of the rack shaft (10) and an axis of a pinion (3) intersect each other at an angle other than 90 degrees, thereby providing a configuration suitable for supporting the rack shaft (10) where a rotational torque occurs when in operation. When depicting directions of pressing forces applied on the rolling surfaces (10b) from the cylindrical rollers (23) respectively with lines, an intersection (K) of these lines is shifted from a center O of the rack shaft (10). It is therefore possible to prevent the rack shaft (10) from rotating and to press rack teeth (10a) against pinion teeth (3a) in a stable state by a resultant force of the pressing forces.
摘要翻译：能够通过电动机输出辅助转向力的电动助力转向装置包括支撑齿条轴（10）的支撑装置（20）。齿条轴10具有支撑装置引导面，即在外周面上至少两部分沿长度方向延伸的滚动面（10b，10b）。支撑装置（20）具有圆筒状的滚子（23），在沿长度方向观察齿条轴（10）的情况下，在与滚动面（10b，10b）交叉的方向上滚动滚动面的滚动面滚动。因此，齿条轴（10）能够以低摩擦力被圆柱滚子（23）支撑，并且设置在齿条轴（10）的外周面上的滚动面（10b，10b）被圆筒状辊（23），从而可以从两个不同的方向支撑齿条轴（10）。因此，齿条轴（10）的轴线和小齿轮（3）的轴线以不同于90度的角度相交，从而提供适于支撑发生旋转扭矩的齿条轴（10）的构造，在运行。当描绘分别用圆柱滚子（23）施加在滚动表面（10b）上的按压力的方向时，这些线的交点（K）从齿条轴（10）的中心O移动。因此，可以防止齿条轴（10）在压力的合力下转动并将齿条齿（10a）抵抗小齿轮齿（3a）保持在稳定状态。
