ABSTRACT:
A ball support structure comprises a ball and a ball support movably holding the ball. The ball support is formed with a ball receiving recess defined by a semispherical portion and a cylindrical portion. A through hole aligning with the ball receiving recess and passing through the ball support is formed. The ball is disposed in the ball receiving recess of the ball support and then the ball support is axially pressed at the peripheral of the ball receiving recess so that metal of part of the ball support flows to contact with the ball thereby to provide a partially spherical portion. The ball is pushed by a rod through the through hole when the partially spherical portion is formed, so that the ball and the semispherical portion has a small gap.
