Abstract
Rotation of a steering wheel (7) is transferred to a steering gear (17) via a pipe-like first shaft (2) and a second shaft (3), which is inserted in the first shaft (2) so that transfer of rotation between the two shafts (2), (3) and relative axial movement between the two shafts (2), (3) are allowable. A ball (23) inserted in a through hole (20) formed through the first shaft (2) is held by a recess (21) formed on the outer surface of the second shaft (3), so that a portion of the ball (23) is projected from the outer surface of the second shaft (3). The inner surface of the first shaft (2) is plasticly deformed by the ball (23) by displacing the recess (21) away from the through hole (20) to form a groove (25).
