ABSTRACT:
In a screw rotor including a female rotor member and a male rotor member rotatable about parallel shafts and respectively while meshing with each other, the forward face flank of the female rotor member is composed of a first flank of the forward face formed by a parabolic curve, and a second flank of the forward face formed by a circular arc of a radius R.sub.2, and the backward face flank of the female rotor member is composed of a first flank of the backward face generated by the backward face tooth top flank of the male rotor member having a radius R.sub.5, and a second flank of the backward face formed by a circular arc of a radius R.sub.3 which is smaller than the radius R.sub.2 of the second flank of the forward face flank. The tooth profile of the male rotor member is essentially formed by the forward face flank and the backward face flank of the female rotor member.
