PURPOSE:To simplify structure and to reduce number of parts by holding the spherical portion of operating lever at the tip of operating lever while fixing a slider block slidable around the operating shaft between sliding guides. CONSTITUTION:An operating lever 32 is fixed to a runner boss system 2 while a slider block 31 for holding the spherical portion of operating lever 32 rotatably is fixed to the tip of operating lever 32 and said slider block 31 is held slidably around the operating shaft between the sliding guides 27, 28. Since 1 lever, 1 slider block system is employed in place of conventional 3 lever, 1 link, 1 slider block system, the structure is simplified and the number of parts can be reduced. |
