Zusammenfassung:	To provide a work machine capable of ensuring stable traveling and steering performance using a control valve with a simple configuration.SOLUTION: A work machine comprises a controller (520) that executes a first control to reduce an increase amount of an opening area of a spool of a directional selector valve (514a, 514b) based on an operation amount of one travel operation lever (332a, 332b) of a pair of left and right travel operation levers (332a, 332b), which has a smaller operation amount, when the pair of left and right travel operation levers (332a, 332b) is tilted in the same direction with different operation amounts.SELECTED DRAWING: Figure 2 【課題】簡易な構成の制御弁により安定的な走行操舵性を確保することができる作業機械を提供する。【解決手段】左右一対の走行操作レバー（３３２ａ，３３２ｂ）が同一方向に異なる操作量で傾倒する時、左右一対の走行操作レバー（３３２ａ，３３２ｂ）のうち、操作量の小さい一方の走行操作レバー（３３２ａ，３３２ｂ）の操作量に基づく方向切換弁（５１４ａ，５１４ｂ）のスプールの開口面積の増加量を減少させる第１制御を実行させる制御装置（５２０）を備える作業機械。【選択図】図２
