ABSTRACT:
According to the present invention, a rolling element7for rotating upon relative movement of both shafts1and2in the axial direction is disposed between three pairs of axial grooves3and5which are formed on the outer peripheral surface of the male shaft1and on the inner peripheral surface of the female shaft2, respectively, a raceway surface element9which is in contact with the rolling element7and an elastic member10for pressurizing the rolling element7against the male shaft1and the female shaft2through the raceway surface element9are interposed between the axial groove3on the male shaft side1and the rolling element7, and a sliding member8for slidably moving upon relative movement of the both shafts1and2in the axial direction is disposed between another three pairs of axial grooves4and6which are formed on the outer peripheral surface of the male shaft1and on the inner peripheral surface of the female shaft2, respectively.
