"SEMI-SPHERICAL AND SELF-DIRECTING WHEEL", characterized by the fact that, on the inner side of the wheel's hemisphere and coinciding with the center of its concavity, a sleeve constituting a single radially protruding sleeve has been arranged piece with said half, which is intended to receive a shaft that acts as an axis and emerges from the center of the inner face of the spherical cap that constitutes the other half of the wheel, which is the carrier of the rolling O-rim, establishing itself the rotating union between both parts, by means of an elastic bushing, contained in the receiving sleeve of the shaft, which for this purpose has a circular groove, in which an open ring fits, whose outer diameter, in the open position, is greater than internal diameter of the bushing that acts as a bearing, thus establishing a drawbar that is resistant to traction, but free to rotate smoothly inside the elastic bushing ..
