For coasting down in a non-rail, channel-shaped roller slide having straight and curved sections, a vehicle comprises a chassis with unsteered wheels, each front wheel being mounted on a supporting member. The axle of each front wheel is arranged with caster behind a pivoting support of the supporting member extending normally thereto. The pivoting movement of the front wheel is limited by coacting stops arranged on the chassis and on the supporting member. |
