Two front wheels are provided at two ends of the wheel support such that the user can be supported with increased stability by the side-by-side arranged front wheels and other wheels that are arranged in one line behind the front wheels. The wheel support has a protrusion sticking up to be movably confined in a guide trench of the front connecting portion so as to limit the change of orientation of the wheel support in relation to the sole to a certain range.
