The invention discloses a chain for a vehicle, belonging to driving parts of non-motor vehicles. The chain comprises a chain link body, a roller with a shaft hole, and a hinged shaft, wherein each chain link body is provided with a pair of chain pieces and at least one tongue-shaped closing plate, one ends of the pair of chain pieces are respectively formed into a small linked crushing plate, and the other ends are respectively formed into a large linked crushing plate, the pair of small linked crushing plates are respectively provided with small crushing plate hinged holes, the pair of large linked crushing plates are respectively provided with large crushing plate hinged holes, and the small linked crushing plates extend into the large linked crushing plates of the adjacent chain link body; the roller with a shaft hole is arranged between the pair of the small linked crushing plates; the hinged shaft penetrates into the large crushing plate hinged holes, the small crushing plate hinged holes and the shaft hole to hinge the small linked crushing plate of one chain pieces of the chain link body with the large linked crushing plate of the other chain pieces of the chain link body; and the tongue-shaped closing plate is formed on the large linked crushing plates. The whole strength of the chain is improved; the tongue-shaped closing plate not only plays roles of dust blocking and draining, but also further improves the strength of the chain link body so that the service life of the chain is prolonged.
