ク・ピニオン伝動装置。 A pair of cylindrical bodies each having a cylindrical shape, each having a notched hole penetrating the inside and outside of the cylinder formed in the center of the lengthwise direction of the cylindrical body, and arranged in parallel with the notched holes facing each other. A guide, a support member that supports the pair of cylindrical guides so as to be movable in directions toward and away from each other, and restrict movement in a direction perpendicular to a plane including the direction of movement, and this support member is fixed. The base plate to be held and the respective cylindrical guides are fitted so that the teeth protruding in opposite directions from the open end surfaces of the respective cylindrical guides and facing each other with threaded teeth in the length direction. A pair of racks are inserted into each cylindrical guide and are slidably held in the respective cylindrical guides. a pinion that engages with both racks at the same time in a portion exposed through the cutout hole of the shaped guide; and a pinion that is installed between the pair of cylindrical guides at positions on both sides of the pinion, respectively;
a pair of equal elastic means for biasing the tooth surfaces of the rack in the direction of pressing the tooth surfaces of the pinion, respectively, through both cylindrical guides; , and a motor that rotates the pinion so as to be able to rotate in forward and reverse directions, and linearly moves the racks by the same distance in opposite directions via the pinion.
