The invention relates to a rear derailleur with a chain stopping block. The rear derailleur comprises two side plates, bolt holes and gaps are machined in the bottoms of the side plates, the gaps are located in the outer edges of the bolt holes, bolts penetrate the bolt holes, tensioning wheels are installed on the bolts, and the chain stopping block is buckled to chain stopping block connecting parts on the two side plates and limited by protrusions on the side plates; and the rear derailleur comprises the two side plates of the same structure, bending parts of the side plates are omitted, and the chain stopping block buckled to the side plates is used for preventing a chain from jumping out. The die manufacturing cost is effectively reduced; and meanwhile, materials and cost are saved, and installation and replacement are very convenient. 种带挡链块的后拨链器，包括两片侧板，侧板的底部加工有螺栓孔及空隙，空隙位于螺栓孔的外沿，螺栓穿过螺栓孔，张紧轮安装在螺栓上，挡链块扣合在两片侧板上的挡链块连接部上并由侧板上的凸起限位；后拨链器包括结构相同的两片侧板，省去了侧板的折弯部，由扣合在侧板上的挡链块来防止链条跳出，有效减小模具的制作成本，同时节省材料、成本，安装更换也非常方便。
