  • Patent number: 11938019
    Abstract: An intraocular lens insertion device which dramatically reduces the possibility that a plunger damages an intraocular lens, and which can safely and surely insert an intraocular lens into an eye is provided. An intraocular lens insertion unit comprises a lens disposing part for disposing an intraocular lens, a plunger for pushing out the intraocular lens disposed at the lens disposing part, a transition part for deforming the intraocular lens pushed out by the plunger, and a nozzle for ejecting the deformed intraocular lens. The plunger has a lens contact part for contacting the outer edge of the intraocular lens, and a protrusive part for pushing the lens contact part downward the intraocular lens by the deformation of the intraocular lens, both lens contact part and protrusive part are provided at the leading end of the plunger.

  • Publication number: 20070209864
    Abstract: 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.

  • Publication number: 20050257634
    Abstract: A rack shaft (110) is formed with a rolling face (110c) narrower than a face width of rack teeth (110a) on the opposite side with an axis line X of the rack shaft being interposed therebetween, and formed with a pair of oblique faces (110b) on both sides with the rolling face (110c) being interposed therebetween, there are further provided a cylindrical roller (123) rolling on the rolling face (110c) of the rack shaft (110) and a support device (120) pressing the cylindrical roller (123) toward the rack shaft (110), and hence the cylindrical roller (123) rolls on the rolling face (110c) when a steering force is transmitted to the rack shaft (110) from a pinion (103a), thereby making it possible to allow a movement of the rack shaft (110) in an axis-line direction with a smaller resisting force.
