PROBLEM TO BE SOLVED: To interpose the vibration generation adapter for an excavator between the front end of an excavator arm and a bucket to generate vibration by itself and not to transmit vibration to the arm side. SOLUTION: This device is constituted of a vibration generation adapter connected to the front end of an arm and a bucket connected to the front side of the adapter. Earth can be dug out by means of the buscket by vibrating of the arm, and the generated vibration from the vibration generation adapter is transmitted to the bucket to carry out a rolling work of earth. In this mechanism, the adapter is constituted of an upper joint body 32 connected to the arm, a lower joint body 34 connected to the bucket, a buffer body interposed between the upper and lower joint bodies 32, 34, a coupling mechanism 33 by which the upper joint body and the lower joint body 32, 34 can be coupled together or uncoupled from each other selectively, and a vibratior mechanism 35 fixed to the lower joint body 34 to generate vibration.
