The invention discloses an anti-thrust structure for an engine cam shaft, an engine with the anti-thrust structure and a vehicle. The engine comprises a cylinder cover and a valve chamber cover arranged at the top of the cylinder cover, the cam shaft is positioned between the cylinder cover and the valve chamber cover, and the anti-thrust structure is arranged between the cylinder cover and the valve chamber cover and matched with one in the cylinder cover and the valve chamber cover through a positioning pin to prevent the cam shaft from moving along the axial direction of the cam shaft. The anti-thrust structure for the engine cam shaft is mounted on the cylinder cover or the valve chamber cover through the positioning pin, the assembly accuracy of the anti-thrust structure and the cylinder cover or the valve chamber cover is effectively ensured, so that the engine is compact in integrated structure and flexible in arrangement, spaces are saved, and cost is reduced.
