PROBLEM TO BE SOLVED: To easily and vertically move a moving member by satisfying specified expressions formed among the lengths of first and second arms, the distance between axis centers of a vertical direction between first and second sliders, a location of a sliding direction of the moving member and the location of the sliding direction of each of the first and second sliders. SOLUTION: When the lengths of first and second arms are defined as L1, L2 and a distance between axis centers of a Z-axis direction to be the vertical direction of first and second sliders is defined as d, a point A moves on a straight line Z=L1, a point B moves on a straight line Z=L1-d and a movable range of the Z-axis direction of a point H becomes 0 to L1+L2-d. When locations of the X-axis direction of the points A and B when the point H moves on a straight line X=x1 are defined as Ax and Bx, respectively, Ax=x1-L1 cosα, Bx=x1- L22-(L1 sinα+d)<2> }<1/2> are formed. Whenαis eliminated from these expressions, a relational expression to be Bx=x1-[L2<2> -[L1 sin cos<-1> (x1-Ax)/L1}+d]<2> ]<1/2> can be deduced.
