    • A telescopic shaft is provided. The telescopic shaft includes a first shaft including a first coupler having an inner circumferential surface including an external straight groove and an external inclination groove formed thereon, the external straight groove having a semi-circular cross section and being formed in parallel to a rotation axis and the external inclination groove having a semi-circular cross section, being inclined with respect to the external straight groove at a predetermined angle, and being shaped like a spiral, a second shaft including a second coupler inserted into the first coupler and having an outer circumferential surface including an internal straight groove and an internal inclination groove formed thereon, the internal straight groove having a semi-circular cross section and corresponding to the external straight groove and the internal inclination groove having a semi-circular cross section, being inclined in an opposite direction to the external inclination groove at a predetermined angle with respect to the internal straight groove, and being shaped like a spiral, and a plurality of balls arranged in a line in an axial direction between the external straight groove and the internal straight groove, one ball being arranged between the external inclination groove and the internal inclination groove, wherein the first shaft and the second shaft are coupled to extend and retract in an axial direction, thereby preventing play from occurring in a circumferential direction and preventing separation of balls.
