  • Patent number: 10711844
    Abstract: A yoke has a yoke main body portion and a thin portion. The thin portion extends from the yoke main body portion toward the shaft, and is thinner than the yoke main body portion. The front end of the shaft is a large-diameter portion that has a larger diameter than an adjacent portion. The yoke main body portion has a yoke general-diameter portion and a step portion. The yoke general-diameter portion has an inner diameter that is substantially equal to an outer diameter of the large-diameter portion. The step portion extends from an end of the yoke general-diameter portion toward an axial line, and has an inner diameter smaller than the outer diameter of the large-diameter portion. The step portion abuts a front end of the large-diameter portion. The thin portion has reduced-radius portions that have smaller radii than the outer radius of the large-diameter portion.

  • Patent number: 10507862
    Abstract: A steering device includes a column pipe, an outer column A, a fixed bracket, a stopper bracket, and a tightening tool. The stopper bracket has a first suspended plate-like portion and a second suspended plate-like portion. A telescopic long hole and an impact absorbing long hole into which a bolt shaft can be inserted from the front side toward the rear side are formed in each of the first and second suspended plate-like portions. A first collapse portion that is bent by colliding with the bolt shaft is provided between the telescopic long hole and the impact absorbing long hole of either the first suspended plate-like portion or the second suspended plate-like portion. A second collapse portion is provided as an inclined side on either the top sides or the bottom sides of the impact absorbing long holes of the first and second suspended plate-like portions.

  • Patent number: 9789897
    Abstract: A steering apparatus includes a column pipe, an outer column, a fixed bracket, a stopper bracket, and a clamping tool. The stopper bracket has a first suspending planar portion and a second suspending planar portion. A telescopic slot and an impact absorbing slot are formed in the first and second suspending planar portions. A first collapsing portion, which is configured as a protruding plate piece positioned between the telescopic slot and the impact absorbing slot of the first suspending planar portion and bent by colliding with a bolt shaft in an event of a secondary collision, is provided in the first and second suspending planar portions. A second collapsing portion, the height dimension of which decreases toward a trailing end is provided in the impact absorbing slot of one of the first suspending planar portion and the second suspending planar portion.
