Claims

[Scope of utility model registration request]

A pair of left and right operating levers that can tilt forward, backward, left and right, a pair of left and right front bell cranks connected to each of the operating levers via a pair of rods, and a pair of control valves connected via rods. In a hydraulic excavator control device comprising two sets of first and second rear bell cranks and a connecting rod connecting the front bell crank and the rear bell crank, the first bell crank and the second bell crank of the rear bell crank are connected to each other. Each bell crank is formed of a shaft and a pipe fitted into the shaft, and these shafts and pipes are provided with protrusions so that the connecting rod and the protrusion can be selectively connected via a supporter. Hydraulic excavator control device.
