WORK MACHINE

PROBLEM TO BE SOLVED: To provide a work machine capable of suppressing contamination of an objective surface of a camera that monitors the surroundings of a vehicle body and confirming a clear image of the camera in the driver's cab.SOLUTION: A camera device 20 is installed in a vehicle body of a hydraulic excavator 1 in which an engine 13, a hydraulic pump driven by the engine 13, a heat exchanger 15 for cooling the engine cooling water, and a fan 17 for generating cooling air for cooling the heat exchanger 15 and the like are accommodated in a power chamber 7. An inlet of an air flow path is formed to face the space on the downstream side of the fan 17 in the power chamber 7, and an outlet of the air flow path is formed to face the objective surface of the camera device 20. Since the downstream side of the heat exchanger 15 or the like in the power chamber 7 becomes a positive pressure by the action of the fan 17, air flows into the air flow path from the positive pressure region and is injected to the objective surface of the camera device 20 to form an air curtain.SELECTED DRAWING: Figure 5 【課題】車体の周囲を監視するカメラの対物面の汚れを抑制し運転室内でカメラの鮮明な映像を確認することができる作業機械を提供する。【解決手段】エンジン１３、エンジン１３で駆動される油圧ポンプ、エンジン冷却水を冷却する熱交換器１５、熱交換器１５等を冷却する冷却風を発生させるファン１７を動力室７に収容した油圧ショベル１の車体にカメラ装置２０を設置して、動力室７におけるファン１７の下流側の空間に入口が、カメラ装置２０の対物面に出口が臨む空気流路を形成する。ファン１７の働きによって動力室７における熱交換器１５等の下流側が陽圧となるので、陽圧領域から空気流路に空気が流れ込んでカメラ装置２０の対物面に噴射されてエアカーテンが形成される。【選択図】 図５
