The utility model relates to a vehicle derailleur structure especially relates to a synchronous ware slider structure. A synchronous ware slider structure, includes the tooth cover, is equipped with tooth hub and synchronous ring below the tooth cover, has cup jointed the combination tooth on the tooth hub, is equipped with the slider between tooth hub and tooth cover, the slider be the adj. Tabular of integrated into one piece, the slider including the bellying that is located the center with be located the jack catch portion of outer fringe, the jack catch joint is on synchronous ring. The utility model provides a manufacturing procedure is simple and convenient, and the dismouting is simple, has realized the low cost, the synchronous ware slider structure of lightweight design, the problem of the synchronous ware modular structure that exists among the prior art complicated, manufacturing procedure is many, and is with high costs, the part is more to lead to the technique that weight is big is solved.
