Ｆ側だけである。As described above, the side plate wear preventing member 21 according to the third prior art is described.
According to this, the loader bucket 1 and the backhoe bucket 11
By performing the excavating function in place of the opening side plates 5, 14, there is an effect of preventing wear of the lower side of each of the opening side plates 5, 14. And when each bucket 1, 11 excavates earth and sand, the wear prevention member 21 is directly involved in the excavation of earth and sand,
Since only the lower part of the wear prevention member 21 in the range of 1/3 to 1/2 of the length in the upward and downward directions is worn, the wear prevention member 21 is worn out in FIG. 10 and FIG. Only the lower F side indicated by middle hatching.
しかるに、従来技術の側板摩耗防止部材21によれば、
下部Ｆ側が1/3〜1/2摩耗しただけで該側板摩耗防止部材
21を新しいものと交換しなければならないため、交換サ

まうことがある。However, according to the side plate wear prevention member 21 of the prior art,
Abrasion prevention member for side plate only when lower F side wears 1/3 to 1/2
Since it is necessary to replace the 21 with a new one, the replacement cycle is short, and at the time of replacement, a new side plate wear preventing member has to be transported from the storage place, which makes the replacement work troublesome. For this reason, depending on the operator, the excavation work or the like may be continued even though the side plate wear prevention member 21 is worn or damaged, and the opening side plates 14 may be damaged.
ここで、各開口部側板14は、バケット11を構成する開
