PROBLEM TO BE SOLVED: To provide a position displacement mechanism capable of applying surely a vertical motion resulting from rotation of a screw shaft to a lever even if an angle of a power point part is changed. SOLUTION: In this position displacement mechanism 32X, 32Y comprising the screw shaft 35 rotated upward or downward and the lever 37 rotated around a journaling point 37C by receiving the pressing force by the screw shaft 35 to thereby displace its position, a ring body 38 is interposed between the tip part 35a of the screw shaft 35 and the power point part 37a of the lever 37, movably near the power point part 37a, to thereby deliver the pressing force by the screw shaft 35 to the power point part 37a.
