A wheel, characterized in that its disc is formed by two plates, each of which, considering only half of the diametrical section of the wheel, is undulated in a double u shape, the upper u being open towards the outside and the lower one open inward; because the peripheral edge of each upper u extends upwards and then inwards, penetrating the material of the elastic band to retain it firmly; because the two bridges of the upper u are welded at their points of contact; and in that the free edges of the plates in the lower u are mutually retained by central seaming.
