ATTACHMENT FOR CONSTRUCTION MACHINE
To provide an attachment for a construction machine allowing a gap adjustment shim to be easily attached.SOLUTION: An attachment 5 for a construction machine 1 comprises: a connection shaft 20; an upper frame 8 and a boom 10 connected by the connection shaft; and a gap adjustment shim 30 adjusting a gap in an axial direction between the upper frame and the boom, wherein the gap adjustment shim 30 is provided with a first component 31 and a second component 32 connected to each other within the gap. Each of the first component and the second component comprises: engagement sections 31a, 32a engageable to each other at one end part; and fastening concave sections 31b, 32b opposing to each other to form a fastening hole 33 at the other end part, which is attached on a circumference of the connection shaft between the engagement section and the fastening concave section.SELECTED DRAWING: Figure 4
【課題】容易に隙間調整シムを取り付け可能な建設機械のアタッチメントを提供する。【解決手段】連結軸２０と、連結軸によって連結されたアッパフレーム８及びブーム１０と、アッパフレーム及びブーム間に生じる軸方向の隙間を調整する隙間調整シム３０と、を有する建設機械１のアタッチメント５であって、隙間調整シム３０は、前記隙間において互いに連結される第１部品３１及び第２部品３２を備え、第１部品及び第２部品はそれぞれ、一端部に、互いに噛合せ可能な噛合せ部３１ａ，３２ａと、他端部に、互いに対向して締結孔３３を形成する締結凹部３１ｂ，３２ｂを有し、噛合せ部及び締結凹部の間において連結軸の外周に取り付けられる。【選択図】図４
