PROBLEM TO BE SOLVED: To provide a technology for preventing separation of a tooth board, when force acts in the juxtaposing direction in a state of disconnecting the connection between the tooth board and a tip edge part, in a tooth board structure juxtaposed and installed in the tip edge part of a bucket of a work machine.SOLUTION: A tooth board 10b comprises a projection part 15b and a projection part 16b. The projection part 15b projects in the vertical direction vertical to an obverse side surface in the obverse side surface on the side butted against a tooth board 10a. The projection part 16b is arranged on the opposite side of a bucket to the projection part 15b. The tooth board 10a comprises a hooking part 13a including an extension part 131a extending in the juxtaposing direction by passing between the projection part 15b and the projection part 16b and a pad part 132a of projecting to the bucket side. A projection part 15c is arranged so as to engage with a pad part 132b of the hooking part 13b when force acts in the juxtaposing direction in a state of disconnecting the connection between a tooth board 10c and a tip edge part of the bucket. |
