Claims

[Claims for Utility Model Registration] The intermediate shaft has constant velocity joints at both ends,
In a vehicle drive shaft that is connected to a shaft on the differential device side and a shaft on the wheel side, the inner member of the constant velocity joint has a recess with a non-circular cross-sectional shape, and a bottom center of the recess. A small-diameter through hole is formed along the axial direction, and the end of the intermediate shaft having a similar cross-sectional shape is fitted into the recess, and the shaft end face and the peripheral edge of the through hole are fitted into the recess. A drive shaft for a vehicle, characterized in that the parts are integrated by welding.
