Abstract
A magnetic coupling device on a toy vehicle has a magnetic element and a fixing element, by means of which the magnetic element is fixed to the vehicle. The fixing element has a dome-shaped coupling surface, which is arranged to be kept in abutment by magnetic attraction against a coupling surface of a coupling device on another toy vehicle. Inside the coupling surface, the fixing element has an inner cavity, in which the magnetic element is arranged to be freely movable.
