PROBLEM TO BE SOLVED: To aim at an operability improvement with a simple configuration in the operation lever device of the work machine equipped with both a radio control device and an operation lever device.SOLUTION: An operation lever device 50 comprises a connecting member 51, a coupling member 52, abase 53 and a lever 54. The connecting member 51 has a rod-like shape, is linked with a flow-rate control valve at its one end and can be displaced in a displacement direction 55. The coupling member 52 is fixed to the other end of the connecting member 51. The coupling member 52 comprises a rack gear 56 provided along a displacement direction 55 of the connecting member 51. The base 53 is rotatably supported around a rotary shaft 58 by the rotary shaft 58. The base 53 comprises a gear 59 concentrically provided with the rotary shaft 58. The lever 54 is connected to the base 53 at one end and is operated by an operator at the other end.SELECTED DRAWING: Figure 6

    【課題】ラジオコントロール装置及び操作レバー装置の双方を備える作業機械の操作レバー装置において、簡単な構成で操作性を高めることを目的とする。【解決手段】操作レバー装置50は、連結部材51と、結合部材52と、基台53と、レバー54とを備える。連結部材51は、棒状であって、一端において流量調整バルブとリンクされており、変位方向55に変位可能である。結合部材52は、連結部材51の他端に固着されている。結合部材52は、連結部材51の変位方向55に沿って設けられたラックギア56を備える。基台53は、回動軸58周りに回動可能に回動軸58に支持されている。基台53は、回動軸58と同心に設けられたギア59を備える。レバー54は、一端において基台53に結合され、他端において作業者に操作される。【選択図】図6
