PROBLEM TO BE SOLVED: To reduce a burden upon an operator and improve the operation efficiency. SOLUTION: A balancing supporter 10 is attached to the bucket 12 of an operation vehicle through a hook part 14. The support arm 26 of the balancing supporter 10 is attached to a circling block 22 so as to be able to circle in a horizontal plane and to swing vertically. A first gas spring 34 is provided between the circling block 22 and the support arm 26 and an angular moment opposite to and corresponding to an angular moment applied to the support arm is applied to the support arm so as to support the support arm 26 with balance at an arbitrary swing position. An operation rod 32 is attached to the tip part of the support arm 26 so as to be inclined freely. A second gas springs 82 and 84 are provided between the support arm 26 and the operation rod 32 can be supported at an arbitrary inclined position.
