PROBLEM TO BE SOLVED: To provide an operation device of a work machine capable of easily grasping an operation position of a single operation mode of an actuator, and performing smooth turning operation while coming into contact with a guide part in a simultaneous operation mode.SOLUTION: An operation device 30 has a joy stick type first operation switch 41, and the first operation switch 41 has a circular first guide ring 36. The first guide ring 36 has a first opening 361, and first to fourth grooves 363 to 366 which correspond to a single operation mode and can receive a part of a tilted joy stick are formed on an inner peripheral surface of the first guide ring, and first to fourth curve surfaces 367 to 370 which correspond to the simultaneous operation mode and guide a turning operation of the joy stick are formed between the respective two grooves.SELECTED DRAWING: Figure 5

    【課題】アクチュエータの単独操作モードの操作位置の把握を容易に行うことが可能で、かつ、同時操作モードにおいてガイド部に当接させながら滑らかな旋回操作が可能な作業機の操作装置を提供する。【解決手段】操作装置30は、ジョイスティック式の第1の操作スイッチ41を有し、第1の操作スイッチ41は、円環状の第1のガイドリング36を有する。第1のガイドリング36は、第1の開口部361を有し、その内周面には、単独操作モードに対応し、傾倒するジョイスティックの一部を受け入れ可能な第1〜第4の溝部363〜366が形成され、これらの各2つの溝部間には、同時操作モードに対応し、ジョイスティックの旋回操作をガイドする第1〜第4の曲面部367〜370が形成されている。【選択図】図5
