CUTTING EDGE FOR WORK MACHINE, BLADE FOR WORK MACHINE AND WORK MACHINE
To provide a cutting edge for a work machine which has a good excavation property and can easily improve durability, and to provide a blade for the work machine and the work machine.SOLUTION: A cutting edge 20 includes a mounting part 21 and an abrasion part 22. The mounting part 21 has a first thickness t1 which is the maximum value of the thickness between a first surface 20A and a second surface 20B. A first portion 22a of the abrasion part 22 has a third surface 20C connected to the first surface 20A, and a fourth surface 20D opposing to the third surface 20C, has a second thickness t2 between the third surface 20C and the fourth surface 20D thinner than the first thickness t1, and has a tip 22T positioned on the opposite side from the mounting part 21. The second portion 22b extends to the opposite side from the third surface 20C from a part of the fourth surface 20D of the first portion 22a, and extends toward the mounting part 21 from the tip 22T of the first portion 22a.SELECTED DRAWING: Figure 5
【課題】掘削性が良好で、耐久性の向上が容易な作業機械用カッティングエッジ、作業機械用ブレードおよび作業機械を提供する。【解決手段】カッティングエッジ２０は、取付部２１と、摩耗部２２とを有している。取付部２１は第１面２０Ａと第２面２０Ｂとの間の厚みの最大値である第１厚みｔ１を有している。摩耗部２２の第１部分２２ａは、第１面２０Ａに連なる第３面２０Ｃと、第３面２０Ｃに対向する第４面２０Ｄとを有し、第１厚みｔ１よりも薄い第３面２０Ｃと第４面２０Ｄとの間の第２厚みｔ２と、取付部２１とは反対側に位置する先端２２Ｔとを有している。第２部分２２ｂは、第１部分２２ａの第４面２０Ｄの一部から第３面２０Ｃとは反対側に延び、かつ第１部分２２ａの先端２２Ｔから取付部２１に向かって延びている。【選択図】図５
