PROBLEM TO BE SOLVED: To provide a vacuum pump that can prevent entry of a foreign matter from an air outlet.SOLUTION: The electrically-driven vacuum pump 1 includes: an air inlet for suctioning air; the air outlet 46 for discharging the air suctioned from the air inlet to the outside; and a cap 22 for covering the air outlet 46. The cap 22 allows the air outlet 46 to communicate to the outside during pump operation to perform air discharge from the air outlet 46, while blocks the communication between the air outlet 46 and the outside during pump stoppage to stop air discharge from the air outlet 46.SELECTED DRAWING: Figure 3
