摘要： Male splines 21 and 23 formed in both the end parts of a torsion bar 5 are fitted and fixed to female splines 22 and 24 formed in an input shaft 2 and an output shaft 3. Further, the number of irregularities of protruding and recessed shaped stoppers 18 and 19 is the same as the number of irregularities of the male splines 21 and 23 formed on the torsion bar 5. The male splines 21 and 23 of both the end parts of the torsion bar 5 have the same phase. Accordingly, even when the torsion bar 5 and both the shafts 2 and 3 are attached to any phase, an angle regulated by the stoppers 18 and 19 when both the shafts 2 and 3 are distorted is substantially the same angle in right and left with respect to a neutral position.

摘要： In an electric power steering apparatus in which steering torque applied on a steering wheel is detected by a torque sensor, and a steering assist torque is generated by an electric motor in accordance with the detected steering torque and transmitted to an output shaft of a steering mechanism with a speed reduced by a worm gear mechanism, the gear meshing position in the worm gear mechanism and the position of the torque sensor are arranged to be substantially coincide with each other with respect to the axial direction of the output shaft. Alternatively, a worm wheel of the worm gear mechanism is directly supported on a housing in a rotatable manner by means of a bearing. A steering shaft and an input shaft of a power assist section are fixedly connected in close contact attained by plastic deformation.

摘要： A precision machining apparatus is structured such that a feed-screw mechanism and an actuator are mounted on a second mount which supports a rotating device that rotates a wheel, and grinding is performed while appropriately adjusting the amount of movement of the second mount in a rough grinding stage through an ultra-precision grinding stage. A posture control device is interposed between a first mount and a rotating device that rotates a grinding target body. The thickness and evenness of the grinding target body are measured by an optical probe and the measurement results are sent to a computer. A feedback command is then sent to the posture control device to reduce the difference between target values and the measurement values and posture control is performed accordingly.
