ク機構。Two actuators A by one switching valve 11,
In a control device for a hydraulic construction machine, etc., which is configured to switch and operate a driver's seat, a U-shaped first lever 2 is rotatably pivoted on the back side of a floorboard 1 of a driver's seat. One piece 2A of the lever 2 is connected to the first rod end 3A having the first rod end 3A.
is connected to the first operating mechanism in the driver's seat via a link mechanism 3, and three fulcrums 5A, 5B, 5C are connected via a support rod 4 near the midpoint of the other piece 2B of the first lever 2. having second
The first fulcrum 5A of the lever 5 is rotatably supported, and the second
A pin 6 is implanted in the second fulcrum 5B of the lever 5, and a second link mechanism 7 equipped with a second rod end 7A having a long hole that loosely fits into the pin 6 is connected to the second link mechanism 7 in the driver's seat. A third fulcrum 5C of the second lever 5 is connected to the control mechanism of the second lever 5.
The second lever 5 is connected to the operating rod of the switching valve 11 via a third link mechanism 8 having a rod end 8A of A stopper 9 that has a means capable of restricting the movement of the first lever 2 and restricts the movement of the other piece 2B in one direction, and a spring 10 that springs the other piece 2B toward the stopper 9 side. A link mechanism of a control device characterized by comprising:
