摘要： A vehicle steering telescopic shaft having a male shaft and a female shaft so fitted to each other as not to be rotatable but to be slidable. First torque transmitting members are disposed between the male shaft and the female shaft, and roll when the male shaft and the female shaft make relative movements in axial directions. Elastic members are disposed adjacent in a radial direction to the first torque transmitting members and restrict them when rotated and apply a pre-load to the male shaft and the female shaft through the first torque transmitting members when not rotated. Second torque transmitting members are provided between the male shaft and the female shaft, and slide when the male shaft and the female shaft make the relative movements in the axial directions, and transmit a torque when rotated.

摘要： 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.

摘要： 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.

摘要： A telescopic shaft for motor vehicle steering assembled in a steering shaft of a motor vehicle and constructed by non-rotatably and slidably fitting a male shaft and a female shaft has a first torque transmission member and a second torque transmission member. The first torque transmission member is interposed, with an elastic body in between, between axial grooves formed in one line in an outer peripheral surface of the male shaft and an inner peripheral surface of the female shaft, respectively. The second torque transmission member is interposed between axial grooves formed in the other one line in the outer peripheral surface of the male shaft and in the inner peripheral surface of the female shaft, respectively. The elastic body has transmission member-side contact portions in contact with the first torque transmission member, groove surface-side contact portions separated in the circumferential direction with predetermined intervals and in contact with groove surfaces of the axial groove of the male shaft or the female shaft, and an urging portion for elastically urging a transmission member-side contact portion and a groove surface-side contact portion in the direction to separate them from each other. Rigidity of the transmission member-side contact portion and that of the groove surface-side contact portions are made different from each other.
