  • Patent number: 9403210
    Abstract: Construction is achieved that is capable of maintaining overall strength of a cylindrical-shaped steering column, while at the same time making it possible to make the thickness part of the steering column thin. An outer column 10b, which is a column member of a steering column is formed by connecting in the axial direction a main portion 18 made using a light metal alloy with a cylindrical member 19 made of an iron-based alloy. A ring 22 made using a metallic material is fitted and fastened to the inner diameter side of the cylindrical member 19 in the connecting section between the main portion 18 and the cylindrical member 19. The inner diameter of the ring 22 is equal to or greater than the inner diameter of the portion of the main portion 18 that is separated in the axial direction from the connecting section with the cylindrical member 19, and is equal to or less than the inner diameter of the cylindrical member 19.

  • Patent number: 9187579
    Abstract: An object of the present invention is to provide a particle-shaped water absorbing agent having a remarkably improved surface color and excellent water-absorbing properties (better water absorption capacity, and lower water soluble content and residual monomer content) at the same time. In order to attain the object, a particle-shaped water absorbing agent according to the present invention is a particle-shaped water absorbing agent whose main component is a polyacrylic acid and/or a salt thereof, the particle-shaped water absorbing agent having a surface color of Hunter b value in a range of ?5 to 10, and having a cross-linking absorption property index (CPI) in a range of 1 to 100, the CPI defined by the following two equations: GEX=(GVs+17)/Ln (water soluble content);??Equation 1: CPI=(GEX/residual monomer content)×100??Equation 3: where GVs is gel volume in saline, Ln (water soluble content) is a logarithm natural of water soluble content.

  • Patent number: 9114829
    Abstract: Construction is achieved wherein a steering wheel can displace smoothly in the forward direction during a secondary collision, even when an electric motor 13a of an electric power steering apparatus protrudes to the side. The distances from the center axis of the steering column 6c to the connecting sections between the installation plate sections 17e, 17f and a portion 34 fastened to the vehicle body are different from each other on both sides of the steering column 6c, such that the distance Le for the installation plate section 17e located on the side where the electric motor 13a is located is shorter than the distance Lf for the installation plate section 17f that is located on the opposite side from the electric motor 13a. The ratio of a separation load that is applied to the installation plate section 17e on the side where the electric motor 13a is located is made to be large.
