PURPOSE:To reduce the number of parts and its assembling manhours and to positively retrain a spline boss at a connecting position in the connecting structure of a rotating axis in which an input side rotating axis is interlocked with and connected to an output side rotating axis by means of the spline boss spline-engaged with the input side rotating axis and the output side rotating axis. CONSTITUTION:Sealing rings 19a and 19b are provided between the inner periphery of a spline boss 18 at both the ends and the outer peripheries of an input side rotating shaft 16 and an output side rotating axis 17. A grease nipple 20 for refueling a spline engagement part is screwed and mounted in the spline boss 18. The screw part 20a of the grease nipple 20 is thrusted into a gap 23 at a facing part between the input side rotating axis 16 and the output side rotating axis 17. |
