PROBLEM TO BE SOLVED: To provide a connecting pin inserting jig capable of easily inserting a connecting pin into a pin hole.SOLUTION: A connecting pin inserting jig is used when a position of a pin hole 7a formed in an arm 7 of a hydraulic excavator and positions of pin holes 8c, 8d formed in bosses 8a, 8b of a work attachment 8 are aligned with each other and a connecting pin 50 is inserted into the pin holes 7a, 8c, 8d of both, and the arm 7 and the work attachment 8 are connected. The connecting pin inserting jig comprises a guide instrument 10 in which a tip of the connecting pin 50 abuts and is held and for guiding the pin holes 7a, 8c, 8d of the arm 7 arranged in a row through the connecting pin 50 from one side P in an axial direction of the pin holes 7a, 8c, 8d to the other side Q, and a guide ring 30 forming a ring shape which is disposed inside the pin hole 8d located on the other side Q in the axial direction among the pin hole 7a of the arm 7 and the pin holes 8c, 8d of the work attachment 8 to insert and guide the guide instrument 10.SELECTED DRAWING: Figure 5
【課題】連結ピンを容易にピン穴に挿入することができる連結ピン挿入ジグを提供する【解決手段】油圧ショベルのアーム７に形成されたピン穴７ａの位置と、作業アタッチメント８のボス８ａ，８ｂに形成されたピン穴８ｃ，８ｄの位置とを一致させ、両者のピン穴７ａ，８ｃ，８ｄに連結ピン５０を挿入してアーム７と作業アタッチメント８とを連結する際に用いる連結ピン挿入ジグであって、連結ピン５０の先端が突き当てられて保持され、一列に並んだアーム７のピン穴７ａ，８ｃ，８ｄにピン穴７ａ，８ｃ，８ｄの軸方向の一方側Ｐから他方側Ｑに連結ピン５０を通して誘導する誘導器１０と、リング状をなし、アーム７のピン穴７ａ及び作業アタッチメント８のピン穴８ｃ，８ｄのうち、軸方向の他方側Ｑに位置するピン穴８ｄの内部に配置されて誘導器１０を挿入させて誘導するガイドリング３０と、を備える。【選択図】図５
