摘要： A frictional roller transmission comprises a first roller and a second roller disposed around two shafts which are separated from each other in such a manner that the two rollers are not brought into contact, a third roller and a fourth roller which are brought into contact with both the first and second rollers and are disposed between the first roller and the second roller and on an opposite side over a line connecting the center of the first roller and that of the second roller. An angle made by a tangential line between the first roller and the third roller (or the fourth roller) and a tangential line between the second roller and the third roller (or the fourth roller) is set at two times as large as an angle of friction obtained from a coefficient of friction between the respective rollers or smaller.

摘要： A plural number of grooves, circumferentially spaced, are formed in a surrounded portion of a first rotary shaft made of magnetic material. A thin tubular member made of conductive and nonmagnetic material, is integrally coupled with a second rotary shaft in the rotation direction, while surrounding the surrounded portion of the first rotary shaft. A plural number of windows are formed in the tubular member. The windows are arrayed so as to partially overlap with the grooves, respectively. An overlapping area of the window and the groove associated therewith is varied in accordance with a relative turn of the tubular member to the surrounded portion. The portions of the tubular member having the windows formed therein are surrounded by coils. The self-induction electromotive force of each of the coils is measured. A torque is detected on the basis of the self-induction electromotive forces measured. An axial length of each of the windows is longer than an axial length of each of the coils but shorter than an axial length of each of yokes for holding the coils. A circumferential width of each of the grooves of the surrounded portion is wider than that of a raised part of the surrounded portion between adjacent ones of the grooves. A side wall of each of the grooves is raised in a radial direction of the first rotary shaft.

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。
