Abstract
A tapered coupling structure allows a tapered shaft to be coupled to and decoupled from a hub without the use of an 0-ring. The tapered shaft is provided with a taper part on the side that is coupled to the hub, and the hub is provided with a high-rigidity part having a thickness in the radial direction larger than that of other regions and having a high rigidity in the radial direction. An oil groove formed in the outer peripheral surface of the taper part to feed oil to the coupling surfaces of the taper part and the hub is provided in a region corresponding to the high-rigidity part in the axial direction.
