PURPOSE:To facilitate fitting by forming spline ends of a spline shaft type first joint so as to suit to the spherical ends thereof, and forming a shaft hole with an inner diameter corresponding to the outer diameter of the first joint on a socket type second joint and a tapered pilot part on one of the splines. CONSTITUTION:Tip of a first spline shaft joint 1 is spherically formed, while an end of a spline 1a is tapered so as to suit to the spherical tip. A front shaft hole 21 in which the spline shaft 1 is insertable is formed on a socket type second joint 2, with a chamfered part 21a, and spline grooves 22 are formed contiguously therewith. At least one of the spline grooves has a tapered extended part 23. Fitting is easily and smoothly carried out with this arrangement even if some dislocation is generated on the axes of the first and second joints 1, 2. |
