Abstract
The torque transmission shaft has a shaft having a hollow tubular shape and a clamp. The shaft has a connecting portion integral with the shaft at one axial end portion, a slit extending in the axial direction in a portion on the other axial end side and opens on the other side in the axial direction, and a female serration on the inner circumferential surface of the other axial end portion. The clamp is separate from the shaft and has a non-continuous portion at one location in the circumferential direction, a pair of flange portions on both sides of the non-continuous portion, and a connecting portion connecting the pair of flange portions in the circumferential direction. The clamp is externally fitted and fixed to the other axial end portion of the shaft and reduces the diameter of the other axial end side portion of the shaft.
