  • Steering device
    Patent number: 8991864
    Abstract: A steering device easily sets an absorption amount of impact energy to a predetermined magnitude at a time when a female male shaft and a male shaft undergo relative contraction upon occurrence of a vehicle collision. If the male shaft undergoes contraction by a length against the female shaft, a serrated edge on a right-end surface of the female shaft is butted against a left-end surface of an impact-energy absorption part. Then, the serrated edge of a female serration is firmly butted against a left-end surface of the impact-energy absorption part to undergo plastic deformation, whereupon resistance to collapsing increases, thereby absorbing impact energy.
