ABSTRACT:
The self-orientatable twin castor has a support made of plastics for a pair of coaxial wheels. The support is constituted by a tubular hub with which a substantially semicircular wall, arranged in the median plane of the castor, is rigidly associated in a perpendicular manner. A semi-cylindrical casing made of metal is associated with the edge of the wall and has wings for positioning and retaining it on the edge of the semi-circular wall.
