The ball holder has an essentially cylindrical tubular section, an annular flange, which is angled outwards from the upper end of said tubular section and has a downwardly arched ball guide channel, and a support web which protrudes outwards at the lower end of the tubular section. The holding web of the roller carrier protrudes inwards between the upper ball guide channel and the support web and is rotatably guided between the said web and the upper balls arranged in the upper ball guide channel of the ball holder. |
