ABSTRACT:
A twin-wheel castor has a moulded body with a through bearing bore in which stub axles of twin moulded wheels are received. The axles have circumferential grooves respectively engaged by two axially-spaced circumferential series of internal body projections moulded within the through bore of the body. The projections are arranged with the two series thereof angularly staggered so that in axial projection no two projections overlap. The engagement of the projections with the axle grooves provides positive retention of the wheels with snap-on assembly thereof to the body.
