Abstract
A speed measuring device for a beach buggy includes a chain wheel rotated by the engine of a buggy, a connecting tube firmly connected to the chain wheel, a bearing fitted in the connecting tube, a gear set, and a fixing unit combined together. The fixing plate, the gear set, the connecting tube and the bearing are assembled together with an elongate rod with thread formed in the lower end portion and then fixed with the chain wheel. Then a hole base is formed on a rear small diameter portion of the gear set for a cable to extend in to transmit speed of the rotating chain wheel to a speedometer for a user to know the speed of the beach buggy.
