To increase strength of a pin body of a fitting pin assembly even when constituting the pin body by two members.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. The bolt 13 causes the first and second pin bodies 11 and 12 to be fastened and fixed in a state in which planar tips abut on each other.SELECTED DRAWING: Figure 3
【課題】取付ピン組立体のピン本体を２つの部材によって構成しながらも、その強度を高める。【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及び第２ピン本体１２は、平面状の先端同士が当接した状態でボルト１３により締結固定されている。【選択図】図３
