To provide a cooling device capable of stably supporting a motor while effectively exhibiting air blowing performance of a fan.SOLUTION: Cooling devices 40, 80 are provided in a work machine. A shroud 50 covering a fan 60 and a motor 70 is provided adjacent to the cooler 40 cooling driving devices 20, 21 installed in a machine body 3. The shroud 50 includes an end wall part 50a having an opened ventilation port 51 and a side wall part 50b surrounding the circumferences of the fan 60 and the motor 70. The shroud 50 further includes a pair of beam members 53, 53 installed to extend in almost parallel with each other and a support table 55 installed on the beam members. The motor 70 is mounted onto the support table 55.SELECTED DRAWING: Figure 4A 【課題】ファンの送風性能を効果的に発揮させながら、モータを安定して支持できる冷却装置を実現する。【解決手段】作業機械が備える冷却装置４０，８０である。機械本体３に設置されている駆動装置２０，２１を冷却する冷却器４０に隣接し、ファン６０およびモータ７０に被さるシュラウド５０を備える。シュラウド５０は、通風口５１が開口する端壁部５０ａと、ファン６０およびモータ７０の周囲を覆う側壁部５０ｂとを有している。シュラウド５０が更に、互いに略平行して延びるように架設された一対の梁部材５３，５３と、これらに架設された支持台５５とを有し、支持台５５にモータ７０が取り付けられている。【選択図】図４Ａ
