PROBLEM TO BE SOLVED: To easily connect a male spline shaft to a connected shaft of a specimen even if these shafts are not aligned with each other and to absorb vibration. SOLUTION: The male spline shaft 4 and the connected shaft 12 of the specimen 1 are connected to each other through a universal joint 5 and a female spline shaft 7. A support part 21 is supported on a suspending part 14 movably supported in the axial direction of the connected shaft 12 movably in the direction perpendicular to the axis of the connected shaft 12. The movement of the support part 21 is constrained by a first floating spring 29. Furthermore, the female spline shaft 7 is supported by rotating bearings 18, the rotating bearings 18 are supported by spherical bearings 20, a movable shaft 24 connected to the spherical bearings 20 at its lower part is vertically movably inserted into the support part 21, and a balance spring 25 is installed between the movable shaft 24 and the support part 21.
