The utility model discloses an idle wheel assembly of an engine, the engine and a vehicle, and relates to the technical field of vehicles. The idle wheel assembly comprises an idle wheel shaft, two bushings and an idle wheel, the idle wheel shaft penetrates through the two bushings, the two bushings are sleeved with the idle wheel, the bushings are provided with matching faces matched with the idle wheel shaft and guide faces located at the two ends of the matching faces, and the guide faces are matched with the idle wheel shaft from the end, away from the other bush, of one bush to the end, close to the other bush, of the other bush. And the inner diameter of the matching surface is gradually reduced. From the end, away from the other lining, of one lining to the end, close to the other lining, of the lining, the matching face of the lining is constructed to be of the structural form with the inner diameter gradually reduced, the edge load of the idle wheel assembly can be reduced, the contact stress of the idle wheel assembly can be reduced, and therefore the service life of the idle wheel assembly can be prolonged, and the service life of the idle wheel assembly can be prolonged. And the transmission performance of the timing chain system of the engine can be improved.
