Abstract
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.
