PURPOSE:To enable a plurality of straight lined operation machines to be easily operated in synchronization with each other without any special devices by connecting mechanically them to a drive source. CONSTITUTION:A flap 2 is operated by running in parallel two straight lined operation machines 3, 4 driven by a motor 5. Namely, connecting pins in the upper connections 6 of respective operating rods 20 and input shafts 12 in two straight lined operation machines 3, 4 are mounted in parallel to the axis of the flap 2, and the respective input shaft 12 are connected to a rotary shaft of the motor 5 through a transmitting shaft 7 and a flexible coupling 8. The input shafts 12 of the respective straight lined operation machines 3, 4 are driven through the drive shaft of the motor 5 to vertically move the operating rods 20 synchronously. |
