PROBLEM TO BE SOLVED: To provide a working machine which can bring the left and right inclination posture of a working device to a target posture as quick as possible while suppressing hunting, and can perform rolling control.SOLUTION: A working machine comprises: a working device connected to a traveling machine body so as to freely change a left and right inclination posture rolling operation means 7 capable of freely changing the left and right inclination posture of the working device inclination angle detection means 42 for detecting a left and right inclination angle of the working device and control means 45 for controlling the rolling operation means 7 on the basis of a deviation between the detection inclination angle detected by the inclination angle detection means 42 and a preset set inclination angle as well as a control target value determined by control gain. The control means 45 reduces the gain with respect to a proportional element as the deviation becomes larger.COPYRIGHT: (C)2016,JPO&INPIT【課題】ハンチングを抑制しながら、できるだけ迅速に作業装置の左右傾斜姿勢を目標姿勢にすることが可能なローリング制御を行える作業機を提供する。【解決手段】左右傾斜姿勢を変更自在に走行機体に連結された作業装置と、作業装置の左右傾斜姿勢を変更操作自在なローリング操作手段7と、作業装置の左右傾斜角を検出する傾斜角検出手段42と、傾斜角検出手段42にて検出される検出傾斜角と予め設定された設定傾斜角との偏差及び制御ゲインにより求めた制御目標値に基づいて、ローリング操作手段7を制御する制御手段45とが備えられ、制御手段45は、偏差が大きいほど比例要素に対するゲインを小さくするようになっている。【選択図】図5
