Abstract: The invention is a rattle particularly for use at sporting events to generate an interesting noise. The rattle is preferably manufactured by plastic injection moulding and has two components only, namely a handle and a rotor journalled for relative rotation therebetween. The handle has a grip portion, and a toothed portion remote from the grip portion and preferably the toothed portion is manufactured by moulding integrally with the grip portion. The rotor has at least one vane adapted to sweep the toothed portion as the rotor rotates relative thereto and is assembled onto the handle by passing the toothed portion axially. A retainer retains the rotor and handle together while permitting said relative rotation. Preferably, the toothed portion has two sets of teeth and the rotor has twin vanes to sweep respective teeth.
