Abstract (en)
The wheel (1) has three elastic arms (5) placed in equilateral triangle and defining a triangular opening (7) to receive an axle (8) with circular section. The axle has a diameter greater than that of a circle inscribed in a triangle-shaped outline of the opening such that the axle elastically deforms the arms when it is introduced in the opening. The arms are deformed so that the wheel is maintained on the axle by elastic tightening exerted on the axle by the arms.
