Claims

[Scope of utility model registration request]

In the angle control device for a work machine, which controls the horizontal tilt angle of the work machine by detecting the horizontal tilt angle of the work machine with respect to a reference plane and driving the connecting member between the work machine and the machine to expand and contract, In contrast, a detector is provided to detect the expansion/contraction state of the connecting member when the work equipment is not tilted in either the left or right direction, and the work equipment is operated to move the work equipment to the upper evacuation position with respect to the machine. 2. An angle control device for a working machine, wherein the angle control device controls the tilting angle of the working machine in the left-right direction based on the detection result of the detector.
