Abstract: Low cost construction of a steering apparatus is provided that is capable of protecting an operator's knees 28 during an automobile collision. A tilted plate 30 is arranged below and behind a bottom end section of a housing 21 which is a component of an electric power assist mechanism 20 connected to a front end section of a steering column 9. In case that the automobile is in a collision, automobile equipment 29 that moves forward under pressure from the driver's knees hits against a bottom surface of the tilted plate. This allows the impact energy to be absorbed by the elasticity or deformation of the tilted plate 30 during impact, and after impact as well, the automobile equipment 29 to move in a direction along the bottom surface of the tilted plate.

Abstract: A telescopic shaft for steering of a vehicle is assembled in a steering shaft and includes a male shaft and a female shaft that are so fitted as not to be rotatable but to be slidable. Rolling members are fitted through an elastic body for pre-load between at least a pair of axially-extending grooves formed in an outer peripheral surface of the male shaft and in an inner peripheral surface of the female shaft. A slide member is fitted in between at least another pair of axially-extending grooves formed in the outer peripheral surface of the male shaft and in the inner peripheral surface of the female shaft. When a steering toque is equal to or smaller than a predetermined level, the elastic body for the pre-load exhibits a low rigidity characteristic as the elastic body performs pre-load action. When the steering torque is equal to or larger than the predetermined level, the slide member exhibits a high rigidity characteristic as the slide member engages with the pair of axially extending grooves.

Abstract: A flanged hexagon head bolt can fasten the bolt by a stable fastening axial force, and can stop rotating the fastened bolt. When the bolt is fastened, a flat bearing face of a circular disk shape flange is brought into face contact with a flat bearing face of a flange portion. Up to the stage, the flanged hexagon head bolt is the same as a bolt which does not have recessed and protruded portions, a variation in a fastening torque is small, and a fastening axial force of the bolt is stabilized. When the bolt is further fastened, the bearing face of the flange portion is inclined, and the recessed and protruded portions of the circular disk shape flange bite an inclined root portion of the bearing face of the flange portion.
