PROBLEM TO BE SOLVED: To provide a bucket link having a hoist hook attaining safety of excavation transport and crane work, improve durability by ensuring strength in a simple and weight lightened structure, additionally to be capable of operating the hoist hook easily mounted/removed and surely fixed to a storage position. SOLUTION: This bucket link 10 has a pair of right/left side parts 17, 17 and a sheet of bottom part 18 partitioning a hoist hook receiving space 19. The side part 17 is extended in spread out shape from a side of a first boss 20 on the cylinder side toward the side of a second boss 21 on the bucket side, the bottom part 18 is extended almost horizontally from the peripheral edge intermediate of the first boss 20 on the cylinder side toward the peripheral edge lower end of the second boss 21 on the bucket side, in addition by providing to protrude in the bottom part 18 a reinforce plate 34, 35 reinforcing an opening peripheral part of a first cutout part 32 on the cylinder side and an opening peripheral part of a second cutout 33 on the bucket side, strength against tensile stress and compression stress can be ensured by a simplified structure arranging a sheet of the bottom part 18 between the side parts 17, additionally even strength against torsional stress can be enhanced, further with the bucket link 10 obtained lightening weight and providing a high quality.
