PROBLEM TO BE SOLVED: To provide a highly accurate multiplying conversion mechanism for oscillating amount which can convert the oscillating amount of a combination of a plurality of levers at a fixed amplification factor without remarkably changing members even when the oscillating range of the combination becomes wider. SOLUTION: In a multiplying conversion mechanism which converts the oscillating amount S of a first arm 141 attached to a first shaft section 5 in a swingable state into an oscillating amountθby means of an adjacent second arm 26, the moving surface 141A which transmits the oscillation of the first arm 141 to the transmission pin 28A of the second arm 26 is inclined against the neutral axis M of the mechanism. Therefore, an amplitude factor K(θ/S) can be stabilized over the wide range ofθwithout being affected by the movement of the pin 28A in the direction of the neutral axis M.
