PROBLEM TO BE SOLVED: To perform easily a work to connect/separate a bearing unit 1b for supporting a wheel and a constant velocity joint 2b without using a special tool. SOLUTION: Several balls 49, 49 are bridged between a part inner peripheral face of a hub 4a forming the bearing unit 1b for supporting wheel and several holes 48, 48 formed on a part of a spline shaft 17 to prevent the spline shaft 17 from coming out from a spline hole 14. The balls 49, 49 are abutted on an outer peripheral face of a part where a part of a supporting member 37 supported on the spline shaft 17 has a larger outside diameter. When a separation work is performed, the balls 49, 49 are faced to an outer peripheral face where a part of the supporting member 37 has a smaller outside diameter by having the supporting member 37 displaced relatively to an axial direction to the spline shaft 17. |
