An inner diameter that is larger than the diameter of the power transmission roller of the rotating plate attached to the power transmission roller according to claim 1 and that does not contact the power transmission roller. The cylindrical plate is attached so as to be concentric with the rotating plate, and a power transmission roller is rotatably attached to the inner diameter surface of the cylindrical plate on a support shaft protruding from the inner diameter surface of the cylindrical plate at a required interval. A cylindrical plate having an outer diameter smaller than the diameter of the power transmission roller attached to the rotating plate and not in contact with these power transmitting rollers is attached to the rotating plate so as to be concentric with the rotating plate. A power transmission roller is rotatably attached on a support shaft protruding from the outer diameter surface of the cylindrical plate at a required interval, and each of the power transmission rollers attached to the rotary plate and the two cylindrical plates is screwed. Screw The screw is arranged in parallel with the rotary plate so as to disengage the grooves formed in the side face of the recess formed between the blade and the rotating plate and the two cylindrical plates by an external force to rotate the A speed increasing device, wherein the screw is configured to rotate via a power transmission roller attached to a rotating plate and the two cylindrical plates. An inner diameter that is larger than the diameter of the power transmission roller of the rotating plate attached to the power transmission roller according to claim 1 and that does not contact the power transmission roller. The cylindrical plate is attached so as to be concentric with the rotating plate, and a power transmission roller is rotatably attached to the inner diameter surface of the cylindrical plate on a support shaft protruding from the inner diameter surface of the cylindrical plate. A rotating plate having an outer diameter equal to or larger than the outer diameter of the cylindrical plate is attached to a side surface of the cylindrical plate to which the rotating plate is not attached, and is concentric with the cylindrical plate. A power transmission roller is attached on a support shaft protruding from the side surface of the rotating plate to the cylindrical plate side at a required interval on a small diameter circumference, and is attached to the two rotating plates and the cylindrical plate. Each power transmission low There are disposed in parallel the screw and the two rotating plates as disengaged in a groove formed in the side face of the recess formed between the spiral blade of the screw, the rotation plate and two said external force When the cylindrical plate rotates, the speed increasing device is configured such that the screw rotates through the two rotating plates and the power transmission roller attached to the cylindrical plate. The outer surface of the rotating plate with the power transmission roller according to claim 1 is smaller than the diameter of the rotating plate with which the power transmission roller is attached and is not in contact with the power transmission roller. A cylindrical plate with a diameter is attached so as to be concentric with the rotating plate, and a power transmission roller is attached to the outer diameter surface of the cylindrical plate at a required interval so as to be rotatable on a support shaft protruding from the outer diameter surface of the cylindrical plate. A rotating plate having a diameter larger than the outer diameter of the cylindrical plate is attached to a side surface of the cylindrical plate to which the rotating plate is not attached, so that the rotating plate is concentric with the cylindrical plate. A power transmission roller is attached at a required interval on a circumference having a diameter larger than the outer diameter so as to be freely rotatable on a support shaft protruding from the side surface of the rotating plate toward the cylindrical plate, and the two rotating plates and the cylindrical plate are provided. Each power transmission robot attached to La is arranged in parallel this screw and the two rotating plates as disengagement grooves formed on the side surface of the concave portion formed between the spiral blade of the screw, the rotating plate of two said external force When the cylindrical plate rotates, the speed increasing device is configured such that the screw rotates through the two rotating plates and the power transmission roller attached to the cylindrical plate.   The gearbox according to any one of claims 1 to 7, wherein a gear is formed on an outer peripheral portion of the spiral blade of the screw.
