PROBLEM TO BE SOLVED: To provide a technology for suppressing wear of a tip edge part of a bucket of a work machine, using a tooth board fitted at the top edge part of the bucket.SOLUTION: A tooth board 7b is fitted onto a bucket of a work machine, using an adaptor fitted at a top edge part of the bucket. Specifically, the tooth board 7b includes an engaging part 71b, a base plate 73b, and a tongue piece 75b. The engaging part 71b is disposed at almost a center of the tooth board on a side fitted on the bucket, the engaging part being engaged with the adaptor. A right side part of the base plate 73b is located on a right side of the engaging part 71b. The tongue piece 75b is located on a left side of the engaging part 71b, and has an inclined part 751b. The inclined part 751b is inclined upward toward the top edge part of the bucket when the tooth board 7b is fitted on the bucket and is mounted on a horizontal surface, such that the inclined bucket is located higher than the top edge part of the bucket.SELECTED DRAWING: Figure 6 |
