To provide a loader working machine achieved in a simple structure, reduced in spatial restriction and enlarged in a lifting range of an arm.SOLUTION: When a direction selector valve 534 for an arm for switching a route of supplying hydraulic fluid from a first hydraulic pump 512 by operating an arm operation lever 207, is switched to the direction of raising an arm 301, the hydraulic fluid is also supplied to a bucket cylinder 304 together with an arm cylinder 302. Thus, a bucket 303 swings interlocking with rise of the arm 301.SELECTED DRAWING: Figure 2 【課題】簡素な構造で実現できてスペースの制約も低減され、また、アームの揚送範囲を拡大させることができるローダ作業機を提供する。【解決手段】アーム操作レバー２０７の操作により第１油圧ポンプ５１２からの作動油を供給するルートを切り換えるためのアーム用方向切換弁５３４がアーム３０１を上昇させる方向に切り換えられた場合には、作動油がアームシリンダ３０２とともにバケットシリンダ３０４にも供給されることで、アーム３０１の上昇に連動してバケット３０３が揺動する。【選択図】図２
