Abstract

【課題】つば部及び連結ピンの回動を規制するストッパを設けることなく外側部材と内側部材とを相対的に回動可能に保持することができる作業機械の二部材連結構造の提供。 【解決手段】油圧ショベルに設けられるブーム４と、このブーム４の内側に配置されるアーム５と、ブーム４、アーム５のそれぞれのピン孔４ａ，５ａに圧入される外側ブッシング６、内側ブッシング７と、これらの外側ブッシング６の孔６ａ及び内側ブッシング７の孔７ａに挿入され、ブーム４とアーム５の二部材を相対的に回動可能に連結する連結ピン８と、この連結ピン８の両端部のそれぞれに一体に設けられるピン抜け出し規制用のつば部９とを備え、連結ピン８を、外側ブッシング６及び内側ブッシング７の双方に対して相対的に回動可能に設けるとともに、つば部９を、ブーム４に対して回り止めさせることなく外側ブッシング６の外側端面６ｂに対して相対的に摺動可能に設けた構成にしてある。
