To prevent dust on an upstream side and a downstream side of cooling air rather than a filter from blown up toward the filter.SOLUTION: A dust collection device 10 includes a fan 42 generating cooling air, a filter 44 collecting dust D in the cooling air generated by the fan 42, and a blowing-up suppression part 50. The blowing-up suppression part 50 is arranged on an upstream side X1 and a downstream side Z2 rather than the filter 44. The blowing-up suppression part 50 includes a plurality of members 60 arranged at intervals mutually. Each of the members 60 includes a filter opposite surface 61a opposite to the filter 44. The plurality of members 60 overlap each other when viewed from the filter 44.SELECTED DRAWING: Figure 2

    【課題】フィルタよりも冷却風上流側かつ下側にあるダストがフィルタに向かって巻き上がることを抑制する。【解決手段】ダスト捕集装置10は、冷却風を発生させるファン42と、ファン42が発生させた冷却風中のダストDを捕集するフィルタ44と、巻上抑制部50と、を備える。巻上抑制部50は、フィルタ44よりも上流側X1かつ下側Z2に配置される。巻上抑制部50は、互いに間隔をあけて配置される複数の部材60を備える。それぞれの部材60は、フィルタ44を向いたフィルタ対向面61aを備える。フィルタ44から見たときに、複数の部材60どうしが重なる。【選択図】図2
