PURPOSE: To simplify the mounting on an automobile of an equal speed universal joint, a hub and a bearing by making them in one unit.

CONSTITUTION: A hollow shaft 22 extending along the length of an outer wheel 21 of an equal speed universal joint 20 is made one unit and bearing inner wheels 26, 27 are inserted with pressure around the periphery of the shaft 22 with one end of at least the one of the bearing inter wheel extruded from the end of the bearing 22. A bearing outer wheel 30 having a flange 33 in one unit for mounting on the car body is fitted on the bearing inner wheels 26, 27 via two raws of rollers 36, 37. An extended part formed in one unit in the inner diameter side of a hub 39 having in one unit a flange 42 for mounting on the body, is inserted in the inner surface of the shaft 22. The hub 39 and the shaft 22 are fixed by several bolts 50 at the periphery and are connected with the outer wheel 21 in one unit.
