PURPOSE:To facilitate conversion of a control pattern without variation in mounting of an intermediate rod, by varying mounting of a pair of mono levers on a first control levr side, a pair of mono-levers on a second control lever side, and a coupling rod. CONSTITUTION:A first mono-lever 33 on the first control lever 31 side is removably coupled to an arm 22, a second lever 34 to an arm 28, a third mono-lever 37 on the second control lever 32 side to an arm 20, and a fourth mono-lever 38 to an arm 26. An arm 50 and coupling member 48 are removably intercoupled through a coupling rod 47. In variation of a control pattern, the fourth mono- lever 38 is replaced to an arm 23, the third mono-lever 37 to an arm 29, the second mono-lever 34 to an arm 25, and the first mono-lever 33 to an arm 19. Further an arm 27 and a coupling part 55 are coupled to a coupling rod. This facilitates conversion of a control pattern. |
