In the two-shaft Roots-type blower consisting of two rotor parts, the shape of the opening in the housing interior side of the discharge port has an opening length in the rotor axial direction that is slightly smaller than the axial length of the rotor, and an opening in the direction connecting the two shafts. The length is approximately the same as the distance between the two axes, the opening length in the axial direction is longer than the opening length in the direction connecting the two axes, and when the rotor tip passes through the opening. A two-shaft Roots-type blower having a shape in which the length of action of the tip of the rotor on the opening gradually increases at least in its initial range.
