<p>A wheel axle (1.07) and a spring element (1.03) are accommodated concentrically in a supporting structure such as a tubing case (1.01). A wheel nut (1.12) for mounting the wheel axle within the tubing case is located at a position which can be turned from outside to facilitate axle adjustment. An assembly shoe (2) is tiltable about an axis orthogonal to the wheel axle and bolted under or above the skateboard. An independent claim is also included for a skateboard.</p> |
