The wheel comprises a peripheral rim (2) that is connected rigidly to a central hub (3). A supporting unit (8) is formed to present a principal part of a removable screen (7) e.g. personal assistant screen. An interior zone of the wheel is delimited partly at the top by the peripheral rim, and partly at the bottom by the central hub when the wheel is in a position of null angle.</p> |
