A constructive arrangement of a flexible wheel for wheelbarrow or manually tractioned industrial carts is constituted by a single block that comprehends three parts: the outer ring (1), the center wall (2), and the inner ring (3); and the outer ring (1) has on its extremity a tread surface (15), and as tangents on each side it has side tread surfaces (12); and each side tread surface (12) has a plurality of radial cavities (11) spaced along the wheel; and the radial cavities (11) of a side tread surface (12) are not aligned in relation to the radial cavities (11a) of the opposite side tread surface (12a); and the center wall (2) is a flat, solid, ring-shaped wall contained in the central plane which contains the body of the wheel, and on each side of the flat wall there are a plurality of flexible structures (14) radially aligned to the radial cavities (11) contained in the outer ring (1).
