PROBLEM TO BE SOLVED: To provide an extended boom of a hydraulic working vehicle capable of solving such a problem that the extended boom has difficulty in manufacturing at a low cost because high machining tolerances are required when two mounting holes are formed in the extended boom since a pivot for fixing the extended boom and the body can't be made to pass through unless two mounting holes formed in the body side of the hydraulic working vehicle more accurately coincide with two mounting holes formed in the lower part of the extended boom when the extended boom is constituted of one member. SOLUTION: The extended boom 31 of the hydraulic working vehicle 1 is equipped with a working machine 6 and, at the same time, it is constituted of two members of the body member 32 and a connecting member 33.
