SOLUTION: This working machine includes a base machine 23 and a work attachment 24. The work attachment 24 includes a boom 25, the interboom 26 and the arm 27. The interboom 26 is operated by an interboom cylinder 30, and the arm 27 is operated by an arm cylinder 31. On this premise, the mounting points of both cylinders 30, 31 for the interboom 26 and the arm 27 are set to A, B, and the work attachment 24 is folded in three sections on the ground. In this state, both cylinders 30, 31 are mounted in a state of fulfilling two conditions that the mounting point A is located on the lower side while the mounting point B is located on the upper side, and both mounting points A, B are dislocated in the width direction of the interboom.
