Abstract: The vehicular driving shaft is oriented and conveyed vertically around to plural assembling stations where component parts of a first joint unit are assembled to a lower end of the shaft whereupon the shaft is reversed and the component parts of the second joint unit are thereafter assembled to the now lower other end of the shaft. Plural carriers hold the shaft vertically as they are driven intermittently to plural stations, each station having an appropriate assembling device, the stations being grouped to first assemble the first joint unit and then to assemble the second.

Abstract: An assembly station has plural roller assembling units mounted each aligned with one of the axes of the projections on a spider fitted to a shaft which is held in position at the station. A roller setting jig and an outer member assembling jig are alternately moveable to an assembly position at the station in line with an axis of the shaft. The roller setting jig includes a jig body vertically moveable along the axial direction of the shaft and a setting member on the jig body having holding portions for detachably holding the rollers to be assembled. The outer member assembling jig includes an outer member jig body vertically moveable along the axial direction of the shaft and a chuck member on the jig body for clamping the outer member.
