Claims

[Claims for Utility Model Registration] 1. Recesses extending in the axial direction are provided at mutually opposing positions on the inner shaft and the outer shaft into which the inner shaft is loosely fitted, and a plurality of rolling elements are interposed between these recesses. In the spline shaft joint, the diameter of the rolling elements is
A spline shaft joint characterized in that, of the inner shaft and the outer shaft, the torsionally rigid side of the shaft is gradually made smaller as it goes from the base side to the tip side. 2. In a spline shaft joint in which grooves extending in the axial direction are provided at opposing positions of the inner shaft and the outer shaft into which the inner shaft is loosely fitted, and a plurality of rolling elements are interposed between these grooves, the above-mentioned The width of one or both of the grooves on the inner shaft and the grooves on the outer shaft is increased from the base side of the shaft with stronger torsional rigidity to the tip side of the inner shaft and the outer shaft. A spline shaft joint characterized by being gradually widened in accordance with the above.
