Abstract: A Roots pump rotates a plurality of rotors by a pair of rotary shafts to draw gas. Each rotary shaft extends through a rear housing member of the Roots pump. A plurality of stoppers are located on each rotary shafts to integrally rotate with the corresponding rotary shafts, and prevent oil from entering a fifth pump chamber of the Roots pump. A tapered circumferential surface is located about an axis of each rotary shaft. Each tapered circumferential surface is located adjacent to an end surface of the stopper and is closer to an oil zone than the end surface is. Each tapered circumferential surface is formed such that the distance between the circumferential surface and the axis of the rotary shafts increases from the side closer to the pump chamber to the side closer to the oil zone. This effectively prevents oil from entering the pump chamber.
