A ball spline joint (30) interconnecting an inner shaft (5) and an outer shaft (6) in mutually loose-fitted relation as allowing the shafts to integrally rotate and relatively move from each other in an axial direction. Raceway grooves (10, 13) are respectively formed in the inner shaft (5) and the outer shaft (6) in face-to-face relation and are extended in the axial direction (X). A plurality of balls (7) are interposed between the corresponding raceway grooves (10, 13) of the inner shaft (5) and the outer shaft (6), forming an array along the axial direction (X). A resilient member (15, 16) biases an array-end ball (7) in an angled direction relative to the axial direction (X). <IMAGE> |
