PROBLEM TO BE SOLVED: To provide a spiral rotator machine, capable of achieving excellent engagement, securely distributing torque, by achieving excellent operating efficiency by setting curvature formed on a rack as an outline of a rotator. SOLUTION: The device comprises a pair of rotators 10 and 30 engaged with each other to rotate in parallel in a device action space. The rotators 10 and 30 have a plurality of tooth forms 11 and 31, and tooth grooves 12 and 32 between them, which are engaged with each other. Of the rotators, one is a male rotator 10, and its outline is formed of a single rack 70. The other one is a female rotator 30, and its outline is similarly formed of the same rack 70 forming the outline of the male rotator 10. COPYRIGHT: (C)2006,JPO&NCIPI
