A vacuum pump of a vehicle is provided to prevent the vacuum pump from being damaged by easily discharging a lubricant stacked in a case regardless of the rotational direction of a rotor. A vacuum pump of a vehicle comprises a case(53), a lubricant feeding hole formed in the case, a first lubricant exhaust hole(61) formed in the case, and a second lubricant exhaust hole(62) formed in the case. A rotor(51) and a vane(52) are rotated in the case. A lubricant is fed into the case through the lubricant feeding hole. When the rotor rotates in the forward direction, the lubricant is discharged from the case through the first lubricant exhaust hole. When the rotor rotates in the reverse direction, the lubricant is discharged from the case through the second lubricant exhaust hole. |
