A telescopic shaft for vehicle steering has first and second torque transferring members. The first torque transferring member is interposed, with an elastic body in between, between axial grooves formed in an outer peripheral surface of a male shaft and an inner peripheral surface of a female shaft. The second torque transferring member is interposed between other axial grooves formed in the outer peripheral surface of the male shaft and in the inner peripheral surface of the female shaft. The elastic body has transferring-member-side contact portions contacting the first torque transferring member, shaft-side contact portions contacting groove surfaces of the axial groove of the male shaft or the female shaft, and a biasing portion for elastically urging the transferring-member-side contact portions and the shaft-side contact portions away from each other. Rigidity of the transferring-member-side contact portions is different from that of the shaft-side contact portions.
