The invention provides a third rail current collector for a railway vehicle. The third rail current collector for the railway vehicle comprises a fuse, a first mounting seat, a second mounting seat and a sliding block, wherein the first mounting seat is used for installing the fuse; the sliding block is used for being contacted with a third rail; a connecting shaft is penetrated on the second mounting seat; one side of the sliding block is fixedly provided with a skid shoe with at least two cantilevers; the tail end of the skid shoe is sheathed on the connecting shaft and rotates around the connecting shaft; the connecting shaft is also provided with an elastic piece used for tightly pressing the top surface of the sliding block onto the third rail; and a working lead is also connected between the skid shoe and the fuse. According to the third rail current collector for the railway vehicle, which is provided by the embodiment of the invention, power supply guarantee can be reliably provided for the railway vehicle, the connecting intensity between the sliding block and the mounting seat is higher, the working reliability is greatly improved, and the current collector maintenance cost is lowered.
