<p>The slide roller (3) has a brake device (7) provided for braking a rotation of the slide roller during deviation of the slide roller from a basic position about an axis (B), where the axis is arranged at right-angle to another axis (A). A spring element (8) is provided such that it exerts a resetting force on the roller for the rotation about the axis for the basic position. The roller can be tilted about a third axis (C) from a rest position, where the third axis runs at right-angle to the axis (B) and toward the basic position. The roller is fastened to a suspension (17).</p> |
