PURPOSE: To provide a spool operation link capable of simplifying the fitting work and reducing the manufacturing cost. ;CONSTITUTION: A first engaging groove 6 and a second engaging groove 7 are formed on one surface of an operation plate 2 along two sides of a right triangle which are orthogonal to each other, a third engaging groove 9 extending to an approximately center direction is formed at the position of the right angle, and an operation lever is fitted to the prescribed position on the other surface. The first and second engaging grooves are engaged with engaging parts 21a, 22a of a pair of linear spools arranged with the center intervals of (d), and the third engaging groove 9 is engaged with an engaging part 23a of a supporting member. The length (x) of the first engaging groove is set so that the distance (k) between an inlet 7a of the second engaging groove 7 and the center of one linear spool may be smaller than the center interval (d) when the engaging part 21a of one linear spool is located at the position to the farthest end side of the first engaging groove 6.;COPYRIGHT: (C)1996,JPO
