ABSTRACT:
The disc, made of plastic material, is provided with a circular collar coaxial with its central hole and which is provided, diametrically opposed, with two arms bent at 90.degree., each arm terminating with a small tongue the end of which extends beyond the said central hole. These small tongues are intended to engage an annular groove provided in the shaft of the machine at the vicinity of its end. The radial displacements of the small tongues are effected during the deformations of the arms which, due to their elasticity, return the small tongues into position.
