Zusammenfassung:	The present invention relates to a vacuum pump for a vehicle. The purpose of the present invention is to provide a vacuum pump for a vehicle, capable of reducing the noise and the vibration during the discharging operation, by preventing the oil discharged from a discharge hole from being accumulated the surrounding of the discharge hole. To achieve the purpose, provided in the present invention is the vacuum pump for a vehicle, comprising: a housing formed with a chamber inside; a discharge hole communicated with the chamber and formed on the housing; a valve for opening and closing the discharge hole; and a space unit arranged at the surrounding of the discharge hole, having at least a portion of the bottom surface of the housing formed in a groove or a pocket shape. 본 발명은 차량용 진공펌프에 관한 것으로서, 배출구에서 배출된 오일이 배출구 근처에 누적되는 것을 방지하여, 배출 동작시 소음과 진동을 저감할 수 있는 차량용 진공 펌프를 제공하는데 목적이 있다. 이러한 목적을 달성하기 위한 본 발명은, 내부에 챔버가 형성되는 하우징과, 상기 챔버와 연통되며 하우징에 형성되는 배출구와, 상기 배출구를 개폐하는 밸브와, 상기 배출구 주위에 마련되되, 하우징의 하면 중 적어도 일부가 홈 또는 포켓 형태로 마련되는 공간부를 포함하는 것을 특징으로 하는 차량용 진공 펌프를 제공한다.
