Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seal structure in a shovel loader which prevents contents to be contained from sticking to a link structure and also prevents damage of a rotary shaft to increase durability. SOLUTION: A first cover 41 is fitted in a such a state that it is protruded sideway so as to surround the half-peripheral face of a bucket link 21 and one side end face is always slidably brought into contact with the side face of a support arm 17. A second cover 51 is joined with both side faces of the support arm 17 and arranged to cover a range extending from a link rod 25 to the bucket link 21. The lower end of the second cover 51 is protruded to the front end side of the support arm 17 and the lower end is always slidably brought into contact with the outer peripheral face of the first cover 41. A third cover 61 is rotatably fitted to the center of the inside face of the base end wall of the bucket 19 to make it possible to close the gap 30c.
