The present invention relates to a vacuum pump and, more specifically, to a vacuum pump that is designed to change the direction of an intake port formed on a side wall of a housing, according to necessity. The vacuum pump includes: a housing; an ejector part embedded in the housing; and a pressing means provided on the outside of the housing. Particularly, the housing includes two or more parts, including a main part that has the intake port, which are disposed in a line, wherein a stopping member is formed along a contact surface there between. This structure enables the main part to rotate, and thus the direction of the intake port can be changed.
