ー１１内には前方からピストン１２を収容して、ピスト
ン１２は油圧によりシリンダー１１内から前方へと前進
させたりシリンダー１１内へと後退させたりできるよう
に１でおり、またピストン１２内には回転軸２３をベア
リング２４により回転自在に支持させ。回転軸２３の前
方には切削ドラム８を取付け、かつ回転軸２３は掘削機
本体に設けた駆動源と連結させてその駆動源により回転
させるようにした、掘削機における掘削部伸縮装置。A cylinder 11 is attached to the front of the excavator body, and a piston 12 is housed in the cylinder 11 from the front, so that the piston 12 can be moved forward from inside the cylinder 11 or retreated into the cylinder 11 by hydraulic pressure. 1, and a rotary shaft 23 is rotatably supported within the piston 12 by a bearing 24. This is an excavating part extension/retraction device for an excavator, in which a cutting drum 8 is attached to the front of a rotating shaft 23, and the rotating shaft 23 is connected to a drive source provided in the excavator body and rotated by the drive source.
