上記従来の技術において述べたバケットの首振装置は、バケットを前後方向だ けでなく左右方向にも首振りができるので作業範囲および作業場所を容易に変更 または拡大することができるものであって、例えば、掘削機械に取付けた場合に は、断面がV字状を呈する溝や傾斜した溝も掘れるようになる等のように、バケ ットの有用性を高めることができて具合の良いものであったが、左右にもつシリ ンダ15、16等伸縮体が交錯状態を呈して互いに邪魔をし合うために、それほ ど大きく首を振れないという致命的な問題点があった。 The bucket oscillating device described in the above-mentioned prior art can swing the bucket not only in the front-back direction but also in the left-right direction, so that the working range and the working place can be easily changed or expanded. For example, when attached to an excavating machine, the bucket can enhance the usefulness of the bucket, such as being able to excavate a groove having a V-shaped cross section or an inclined groove. However, since the elastic bodies such as the cylinders 15 and 16 on the left and right sides are in a crossed state and interfere with each other, there is a fatal problem that the head cannot be shaken so much.
