PROBLEM TO BE SOLVED: To associatively increase/reduce force in a primitive fashion by using the force action of levers. SOLUTION: In associative reciprocating motion, a lever rod 1 and a lever rod 2 are mounted on a supporting point 3-1 of a board 3 and on a supporting point 3-2 of the board 3, respectively, so that the lever rod 1 and the lever rod 2 are rotatable. A rotation adjuster 1-1 and an adjusting stay 2-1 are connected together with a bolt-nut A. The lever rods 1 and the lever rods 2 are connected together in any number for associating force action. The association of force action is infinitized by providing the rotation adjuster 1-1 and the adjusting stay 2-1 for repeated connection in small and great lever contrasts (for example, the connection of the lever rods 1, 2 and 1, 3 together in the lever contrasts at length contrasts of 2:1, 2:1 and 3:1).
