The present invention relates to a vacuum pump for a vehicle and, more specifically, to a vacuum pump for a vehicle, which has a structure for preventing foreign materials mixed in engine oil of a vehicle from flowing into a vacuum chamber. The vacuum pump for a vehicle comprises: a rotating rotor which is prepared to receive power from a cam shaft; an oil flow path which is inserted into the cam shaft and the rotating rotor and has a nozzle arranged in a longitudinal direction through the cam shaft and the rotating rotor to supply oil to the inside of the rotating rotor; and a guide surface which is formed in one end of the nozzle where the inlet of the oil flow path is formed and guides the foreign materials mixed in the oil to the outer part of one end of the nozzle.
