PURPOSE:To offer a thrust force generating device of simple construction by using a roller equipped with disc-shaped fillets having a twisted profile and a screw roller with a certain thread pitch. CONSTITUTION:A roller 1 is equipped at its periphery with disc-shaped filets 4 having a twisted profile, and segment pieces 3 with a boss hole 5 are placed on the wall of a pipe 6. A screw roller 2 is mounted on the truck side as a drive vehicle. Rotation of this screw roller 2 is transmitted to the fillet-equipped roller 1 and they rotate together to generate a thrust force in parallel to the axis for moving a moving object.
