To protect a head of a bolt constituting a fitting pin assembly, while an increase in weight of an excavation tool is suppressed.SOLUTION: A fitting pin assembly 10 comprises a first pin body 11 for being inserted into first and second through-holes 2b and 3b from a first side part 5 of an excavation tool 2, a second pin body 12 for being inserted into the first and second through-holes 2b and 3b from a second side part 6 of the excavation tool 2, and a bolt 13 that is inserted through the first and second pin bodies 11 and 12 so as to fasten and fix the first and second pin bodies 11 and 12 to each other. A storage recess 11c for accommodating a head 13b of the bolt 13 at an inside of the first through-hole 2b is formed in the pin body 11.SELECTED DRAWING: Figure 3
【課題】掘削具の重量増加を抑制しながらも、取付ピン組立体を構成するボルトの頭を保護する。【解決手段】取付けピン組立体１０は、掘削具２の第１側部５から第１貫通孔２ｂ及び第２貫通孔３ｂに挿入される第１ピン本体１１と、掘削具２の第２側部６から第１貫通孔２ｂ及び第２貫通孔３ｂに挿入される第２ピン本体１２と、第１ピン本体１１及び第２ピン本体１２に挿通されて当該第１ピン本体１１及び第２ピン本体１２を互いに締結固定するボルト１３とを備え、第１ピン本体１１には、第１貫通孔２ｂの内側においてボルト１３の頭１３ｂを収容する収容凹部１１ｃが形成されている。【選択図】図３
