PROBLEM TO BE SOLVED: To easily and freely adjust the clearance of a spline part by dividing a boss part or a spline shaft part, and rotating and displacing the divided members in the mutually opposite direction around the axis. SOLUTION: A spline part is put in a coaxially connected state of a first spline shaft member 16 to a second spline shaft member 18 through a shaft part 28. A tip part 48 of a screw member 50 presses an inclined face of a recess part 30 formed in the shaft part 28 when a screwing-in quantity of the screw member 50 is increased by applying a clearance adjusting mechanism 21 to screw the screw member 50 in a screw hole 46 formed in a cylindrical part 34 of the second spline shaft member 18 in this state. A circumferential directional clearance A between a second tooth part 40 and a third tooth part formed on an inner peripheral wall of a boss part 14 can be freely adjusted by rotating and displacing a first spline shaft member 16 side first tooth part by a prescribed angle in the same circumferential direction to the second spline shaft member 18 side second tooth part 40 according to this. |
