PROBLEM TO BE SOLVED: To prevent an interference in a driving section and a bucket without separately annexing a safety device and a controller by setting an angle formed by a lower shaft connecting a first boom and a second boom and a support on the front side of a canopy or a cabin to an approximately right angle under the state that the first boom is lifted maximally. SOLUTION: The front-section support 7a of a canopy 7 is arranged at the front end of a driving section 9 so that an angle formed by the support 7a and a lower shaft 15 coupling a first boom 10 and a second boom 11 at an approximately right angle under the state, in which the boom 10 elevated maximally. Accordingly, when a bucket 14 is offset left and right, the bucket 14 is moved in approximately parallel with the support 7a in a side view. Since the arm-direction side of the shaft 15 is placed at a position higher than the opposite-direction side under the state, in which the boom 10 is lifted maximally, the bucket 14 is moved from a rear to a front in the side view and the bucket 14 is not brought near to the driving section 9 when the boom 11 is rotated centering around the shaft 15 and the bucket 14 is offset left and right.
