Abstract
A shaft coupling structure for male and female shaft components of a vehicular propeller shaft includes a sleeve shaft having a substantially rigid first end, an annular flange formed therearound at a central location at which the sleeve shaft connects to a tube member, and a reduced diameter portion which extends from the flange into the tube portion. A plurality of splines are formed in the axial direction of the sleeve shaft and are interposed between an inner wall of the rigid first end and a stub yoke which is inserted into the first end for co-rotation therewith. Further, a grease cap, or other lubrication device may be provided at an end of the reduced diameter portion. Also, around the reduced diameter portion, between the inner wall of the tube and the outer side of the reduced diameter portion, a vibration damping device, as well as an insertion guide device may be provided for improving smoothness and reducing operational noise for the shaft coupling structure.
